Unsticking Ourselves from Glue: Migrating PayIt’s Data Pipelines to Argo Workflows and Hera Presented by Matt Menzenski, Senior Software Engineering Manager, Payitgov At PayIt, we’ve been deploying applications to Kubernetes almost since the beginning of the company. Our data workloads, however, have run instead in AWS Glue. This has worked well enough for the reporting use cases that have been the main focus of this team historically. However, at the beginning of 2022, the PayIt data team began building out a new data platform, and in the process, ran into a number of challenges with Glue. In this talk, I will share the difficulties that we encountered with building, deploying, and orchestrating ETL pipelines in AWS Glue, our decision process for moving those workloads into Kubernetes, and the ELT architecture that we’ve arrived at today.

From the DoK Day North America 2022 ( https://youtu.be/YWTa-DiVljY ) Video - https://youtu.be/A1ch4AhKoeQ ABSTRACT If there’s one thing that everyone can agree on - it’s that the sheer scale and complexity of Kubernetes operations is growing constantly. What’s more, cloud native environments are becoming more and more expensive to operate and manage, as well as increasingly difficult to secure. On the bright side, there is a growing ecosystem of exceptional open source tools to help overcome this complexity, and provide greater situational awareness to what’s happening in your many and multiple Kubernetes clusters. In this talk, we’ll take a deep dive on how to understand everything that is happening with stateful workloads in your Kubernetes clusters from health to security - including the management and monitoring of your clusters, troubleshooting and debugging, through full security scanning in multiple data perspectives- from configMaps, Secrets, hostPaths and many more security driven checks for proper role-based access control, vulnerabilities and misconfigurations. We will demonstrate how you can have a 360º-view of your Kubernetes clusters in a single open source dashboard leveraging tools like Lens and Kubescape, and ultimately enforce policies with Open Policy Agent.…

Shifting Left Stateful Applications In Kubernetes // Viktor Farcic (DoK Day North America 2022) 15:52

۳ years پیش15:52

15:52

From the DoK Day North America 2022 ( https://youtu.be/YWTa-DiVljY ) Video - https://youtu.be/LymPjH6HA3E ABSTRACT Stateless apps are easy to manage. More often than not, a Kubernetes Deployment, with a Service, Ingress, and Horizontal Pod Autoscaler (HPA) is enough. Almost everyone can do it. But, when it comes to stateful applications, things become a bit more complicated. We might need a database and storage. We might need to manage database users and schema. We might need to consider quite a few other things. Stateful apps are harder for everyone, especially if we want to shift left and enable developers to do it themselves. In this talk, we'll try to make the management of stateful applications easy for everyone. We'll accomplish that by creating easy-to-consume services that are made specifically for the needs of our organizations. We'll see how to create new Kubernetes Custom Resource Definitions (CRDs) and controllers using Crossplane. Those controllers will envelop all the tools, resources, and processes we might need. As a result, ops can focus on creating such services while everyone else can consume them (create and manage everything related to stateful apps) without opening JIRA tickets and waiting for others to complete their tasks.…

Medical - Healthcare Data on Kubernetes // Olyvia Rakshit & Prasad Dorbala (DoK Day North America 2022) 13:41

۳ years پیش13:41

13:41

From the DoK Day North America 2022 ( https://youtu.be/YWTa-DiVljY ) ABSTRACT Healthcare organizations are transforming their applications and embracing digital platforms for efficient patient care. Today, compute at the edge, plays a critical role in deploying innovative healthcare applications that promise new approaches to patient care. Connected care platforms at scale are turning to Kubernetes infrastructure for deployment of telehealth and telemedicine apps. These kinds of applications often need real time image processing and inferencing at the edge, which in turn, require a distributed application platform on Kubernetes. They also need secure foundations for a regulatory compliant framework for wider adoption. To elaborate further, a distributed platform or a multi-cluster infrastructure is necessary for healthcare applications. All medical application platforms are data intense. For eg. Medical applications that need to stream video data, i.e move large quantities of data need secure connections from edge to cloud. Smart healthcare applications are also seeing the value of multi-cloud deployments. The ability to choose different technologies like AI, data storage systems or some specific relational database systems is driving multi-cloud adoption in healthcare solutions. A multi-cluster connectivity fabric is thus needed for data intensive healthcare applications to distribute across geographical boundaries. The fabric needs to have inbuilt automation and the smarts to make the best use of compute resources in a distributed infrastructure, for improved patient healthcare.…

From the DoK Day North America 2022 ( https://youtu.be/YWTa-DiVljY ) ABSTRACT In the software industry we’re fond of terms that define major trends, like “cloud native”, “Kubernetes native” and “serverless”. As more and more organizations move stateful workloads to Kubernetes, we’ve started to see these terms applied to data infrastructure, where they can get overtaken by marketing hype unless we work to define them. In this talk, we’ll examine two different databases, TiDB and Apache Cassandra, in order to identify what it means for a database to be Kubernetes native and why it matters. We’ll look at points including: - The differences between cloud native, Kubernetes native, and serverless - How databases become Kubernetes native - Benefits of Kubernetes native databases - How Kubernetes can better support databases…

https://go.dok.community/slack https://dok.community We are going to speak about CRDs, and discuss considering them as higher level entities that we normally consider them. CRDs normally are kind of a byproduct of an operator. But in reality, they can be considered as the user-facing API of the operator surface. And as such, we would like to introduce conversations about even standardizing some of them, or creating "specifications" out of some CRDs. Take this for example: there are some CRDs that could be, potentially, common across multiple operators. Think of a CRD to represent an S3 (or any other storage object) bucket. For operators that store data in object stores, each and every one of them are creating their own versions. But shouldn't we have some "standardized" `ObjectStorage` CRD, without a controller, that all could use? We'll be joined by John Sanda of DataStax who works on the K8ssandra project, Alvaro Hernandez who is the CEO of Ongres and Postgres superhero, and Eyar Zilberman Co-Founder and Chief Product Officer at Datree.…

https://go.dok.community/slack https://dok.community/ With: Sebastian Glab - Cloud Architect, CloudCasa by Catalogic Martin Phan - Field CTO – Americas, CloudCasa by Catalogic Bart Farrell - Head of Community, Data on Kubernetes Community ABSTRACT OF THE TALK If you are running or planning a multi-cloud or even a multi-cluster environment, there are several considerations in implementing a data protection solution – especially if you plan on an organic home-grown, do-it-yourself option. This talk will highlight challenges and best practices around centralized management of configuration, credentials, compliance across multiple accounts, regions, providers etc. We will also highlight the deviations in CSI driver implementations of various storage vendors and cloud providers. Finally, we will cover the various recovery options available in the market today. Kubernetes cloud services are popular since they mitigate, but do not eliminate, the difficulties of operating a Kubernetes environment. This is especially true for protecting the stateful configuration and data of your Kubernetes applications, where the inherent high-availability and infrastructure as code are not a substitute for have cloud-native backup and disaster recovery capabilities. Further, many companies now have multi-cloud strategies for their cloud-native applications. These challenges can be addressed with backup applications that are both Kubernetes managed service and multi-cloud aware in order to snapshot, copy, restore, and migrate Kubernetes workloads (resources and data) running on AKS, EKS and GKE. Capturing information from cloud accounts and how the cluster and storage resources are configured allows 1) centralized visibility into all cloud accounts and the clusters and resources in the accounts including for compliance; 2) cross-account, cross-cluster, and cross-region data restores; 3) automation of the cluster and data restores including for Dev, Test, and Production recovery use cases. BIO Sebastian Glab is a Cloud Architect for CloudCasa and he resides in Poland. He is responsible for integrating the different cloud providers with the CloudCasa service, and making sure that all clusters in the cloud service get discovered and protected.

DoK Talks #141 - Dossier: multi-tenant distributed Jupyter Notebooks // Iacoppo Colonnelli & Dario Tranchitella 1:00:10

۳ years پیش1:00:10

1:00:10

https://go.dok.community/slack https://dok.community ABSTRACT OF THE TALK When providing data analysis as a service, one must tackle several problems. Data privacy and protection by design are crucial when working on sensitive data. Performance and scalability are fundamental for compute-intensive workloads, e.g. training Deep Neural Networks. User-friendly interfaces and fast prototyping tools are essential to allow domain experts to experiment with new techniques. Portability and reproducibility are necessary to assess the actual value of results. Kubernetes is the best platform to provide reliable, elastic, and maintainable services. However, Kubernetes alone is not enough to achieve large-scale multi-tenant reproducible data analysis. OOTB support for multi-tenancy is too rough, with only two levels of segregation (i.e. the single namespace or the entire cluster). Offloading computation to off-cluster resources is non-trivial and requires the user's manual configuration. Also, Jupyter Notebooks per se cannot provide much scalability (they execute locally and sequentially) and reproducibility (users can run cells in any order and any number of times). The Dossier platform allows system administrators to manage multi-tenant distributed Jupyter Notebooks at the cluster level in the Kubernetes way, i.e. through CRDs. Namespaces are aggregated in Tenants, and all security and accountability aspects are managed at that level. Each Notebook spawns into a user-dedicated namespace, subject to all Tenant-level constraints. Users can rely on provisioned resources, either in-cluster worker nodes or external resources like HPC facilities. Plus, they can plug their computing nodes in a BYOD fashion. Notebooks are interpreted as distributed workflows, where each cell is a task that one can offload to a different location in charge of its execution. BIO Iacopo Colonnelli is a Computer Science research fellow. He received his Ph.D. with honours in Modeling and Data Science at Università di Torino with a thesis on novel workflow models for heterogeneous distributed systems, and his master’s degree in Computer Engineering from Politecnico di Torino with a thesis on a high-performance parallel tracking algorithm for the ALICE experiment at CERN. His research focuses on both statistical and computational aspects of data analysis at large scale and on workflow modeling and management in heterogeneous distributed architectures. Dario is an SWE that turned DevOps, and he's regretting this choice day by day. Besides making memes on Twitter that gain more reactions than technical discussions, leading the development of Open Source projects at CLASTIX, an Open Source-based start-up focusing on Multi-Tenancy in Kubernetes. KEY TAKE-AWAYS FROM THE TALK From this talk, people will learn: - The different requirements of Data analysis as a service - How to configure for multi-tenancy at the cluster level with Capsule - How to write distributed workflows as Notebooks with Jupyter Workflows - How to combine all these aspects into a single platform: Dossier All the software presented in the talk is OpenSource, so attendees can directly play with them and include them in their experiments with no additional restrictions.…

https://go.dok.community/slack https://dok.community ABSTRACT OF THE TALK Apache Kafka is more than just a messaging broker. It has a rich ecosystem of different components. There are connectors for importing and exporting data, different stream processing libraries, schema registries and a lot more. The first part of this talk will explain the Apache Kafka ecosystem and how the different components can be used to load data from social networks and use stream processing and machine learning to analyze them. The second part will show a demo running on Kubernetes which will use Kafka Connect to load data from Twitter and analyze them using the Kafka Streams API. After this talk, the attendees should be able to better understand the full advantages of the Apache Kafka ecosystem especially with focus on Kafka Connect and Kafka Streams API. And they should be also able to use these components on top of Kubernetes. BIO Jakub works at Red Hat as Senior Principal Software Engineer. He has long-term experience with messaging and currently focuses mainly on Apache Kafka and its integration with Kubernetes. He is one of the maintainers of the Strimzi project which provides tooling for running Apache Kafka on Kubernetes. Before joining Red Hat he worked as messaging and solution architect in the financial industry. KEY TAKE-AWAYS FROM THE TALK The key takeaway of this talk is that Apache Kafka is more than just a messaging broker. It is a platform and ecosystem of different components which can be used to solve complex tasks when dealing with events or processing data. The talk demonstrates this on loading tweets from Twitter and processing them using the different parts of the Kafka ecosystem. The whole talk and its demos are running on Kubernetes using the Strimzi project.

This talk is for believers, those who believe that the author will deliver what the title says. Here’s the promise on what you will see: * Time-series specialized storage and functions on SQL Server. * SQL Server running on Kubernetes. * Using ARM64 (aarch64) nodes. * In reality, without using SQL Server, but rather Postgres Babelfish! The talk will be focused on a demo to show all these components working together. Surely the demo will fail badly, so get ready your rotten tomatoes! The good news is that you will be able to reproduce the demo on your environment too, as all the software used is open source and source code will be provided. BIO Álvaro is a passionate database and software developer. Founder of OnGres (one of the founding sponsors of DoK), he has been dedicated to PostgreSQL and R&D in databases for more than two decades. Álvaro is at heart an open source advocate and developer. He has created software like StackGres, a Platform for running Postgres on Kubernetes. As a well-known member of the PostgreSQL Community, Álvaro founded the non-profit Fundación PostgreSQL and the Spanish PostgreSQL User Group. He has contributed, among others, the SCRAM authentication library to the Postgres JDBC driver. You can find him frequently speaking at PostgreSQL, database, cloud (becoming an AWS Data Hero in 2019), and Java conferences. In the last 10 years, Álvaro has completed more than 100 tech talks ( https://aht.es ). KEY TAKE-AWAYS FROM THE TALK A key to progress is to combine technologies in novel ways to bring new capabilities to environments that typically lack them. For example, using Postgres Babelfish (a SQL Server-compatible Postgres flavor) and Timescaledb (time-series extension for Postgres) we can deliver open source time-series native capabilities on top of SQL Server protocol, available to SQL Server users.…

Why run Postgres in Kubernetes (DoK Day EU 2022) // Gabriele Bartolini 10:02

https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Postgres should run inside your Kubernetes cluster. Yes, inside, not outside Kubernetes. After all, a database should be seen as an application, a special type of application - for which it is legitimate to require an additional level of care and attention. However, the small price you pay for this is worth the return on investment that your organization receives by running microservice applications, plus database combos, inside your Cloud Native infrastructure. In this session, I will cover why it is important to make such a decision. Discover the challenges and the opportunities that running Postgres inside Kubernetes presents. I will discuss what we all expect from a good Postgres operator, including self-healing, high availability, scalability, backup and recovery, performance, and - last but not least - security. I will then go beyond technical aspects to spark conversations about the holistic improvements that running a Cloud Native database brings to your organization. A long time open source programmer and entrepreneur, Gabriele has a degree in Statistics from the University of Florence. After having consistently contributed to the growth of 2ndQuadrant and its members through nurturing a lean and devops culture, he is now leading the Cloud Native initiative at EDB. Gabriele lives in Prato, a small but vibrant city located in the northern part of Tuscany, Italy - known for having hosted the first European PostgreSQL conferences.

What we've learned from running a PostgreSQL managed service on Kubernetes (DoK Day EU 2022) // Oleksii Kliukin 11:06

۳ years پیش11:06

https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Kubernetes is an emerging platform of choice for deploying and running PostgresSQL. Deploying 100 Postgres clusters is as easy as deploying one, and there is no need to tinker with tools like Ansible or Puppet. Resource sharing can be applied when it makes sense, allowing to run multiple Postgres databases in isolation on a single instance, each storing the data on a dedicated persistent volume. There are great open-source tools out there to deal with high-availability and backups than support or can be easily integrated into the Kubernetes workflow. Monitoring and alerting is easy to implement. People reported success in running Postgres on Kubernetes before. But there are also rough edges, like memory management or certain Postgres maintenance operations, such as installing extensions, that normally cause unnecessary database downtimes on Kubernetes. They are less of a problem for in-house deployments, but may become a deciding factor when running a managed service, competing with other such services running on bare-metal servers or virtual machines that are free of those issues. In this talk, I will share some of our learnings from running a managed PostgreSQL/TimescaleDB service on Kubernetes on AWS for a little more than a year: I’ll start with the motivation of running managed PostgreSQL on Kubernetes, the benefits and drawbacks. I’ll describe the architecture of the managed PostgreSQL cloud on Kubernetes I’ll zoom in on how we solved some of the Kubernetes-specific issues within our cloud, such as upgrading extensions without downtimes, taming the dreaded OOM killer, and doing regular maintenance and PostgreSQL major upgrades. I’ll share how open-source tools from the PostgreSQL ecosystem helps us to run the service and explain how we use them in a slightly non-trivial way. Oleksii has been working with PostgresSQL for almost 20 years, and has been deploying Postgres on Kubernetes since 2016, when his team at Zalando started the internal managed PostgreSQL service based on the in-house and open-source postgresql-operator. Around 2015, with some other team members, he stared working on a PostgreSQL HA project that later became Patroni. Long before that he was hacking PosgreSQL source code to implement binary replication on PostgreSQL 7.x, authoring some PostgreSQL extensions and contributing to the core PostgreSQL itself. He started PosgreSQL meetups in Berlin in 2015 and hopes to get back to meeting in-person somewhere in 2022.

https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) “Zero downtime” and “always-on” are illusions. All systems fail sooner or later, whether it’s a regional e-commerce website or a major cloud region hosting thousands of applications. That’s why, instead of chasing these illusions, it’s worth focusing on the nines of availability. Based on true stories, this session walks you through modern data availability and reliability patterns used by architects whose applications withstood major cloud outages. With the focus on the data storage layer and Kubernetes, you’ll learn: * How to architect the data layer in Kubernetes with the server, zone, and region-level resiliency in mind. * How to find a compromise between latency and availability for multi-region deployments. * How to ensure the data layer remains reliable (i.e., always returns expected data) even during a major incident.

https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Serverless promises to change the way we consume software. It allows us to potentially pay for only that which we use and can help drive down operational costs to the minimal amount of resources necessary. Architecting for serverless requires a unique look at app logic and the way it is deployed. It takes a combination of the logical and physical worlds. An architectural pattern has emerged where we can scale ephemeral compute separate from services that need to persist. We use Kubernetes to deliver exactly this. A “serverless” experience that is driven and enabled by compute pods and storage pods. We also have used our experience running thousands of database clusters on Kubernetes to automate the operational expertise of managing a distributed database. In this talk, we will take a dive deep into the architecture of our application and share: * A definition and outline of the challenges of serverless * How we reworked our logic for a serverless approach * How we use Kubernetes to gain serverless autoscaling Jim is a recovering developer turned evangelist who loves useful, cool, cutting-edge tech.

https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Multiple clusters exist in most Kubernetes environments today, and number of clusters will increase overtime. The reasons for having multiple Kubernetes clusters are many, for example, overcoming scale limits, reducing complexity, geo separation, redundancy and having separate production, staging, and development environments. Once you have multiple K8S clusters, it can be useful to have the ability to easily move or duplicate workloads across these different clusters. Kubernetes does not have a native method to allow migration or duplication of workloads across clusters. Fortunately, there are tools that provide this functionality. In this presentation we will explore the different uses cases for cross cluster migration, and what is involved, and how these migration tools work. We'll cover some popular uses cases, such as, Disaster Recovery, Test/Dev, and performance testing. Migration could entail moving the entire cluster, or individual workloads. The components that need to be moved would include configuration and resources stored in etcd, and persistent data residing on PVCs. We'll cover the uses cases and challenges for migration, and run through an example of using one of these migration tools.…

In this talk, we share the experience of running Kafka as a stateful Kubernetes workload in a cloud-native environment using the open-source Koperator and the tools we built to automate the whole lifecycle. While running a stateful service like Kafka on Kubernetes may be intimidating at the first glance, we share our thought process, the tools, and the results that can make this a reality in any organization. The Kubernetes Operator pattern helped us automate all the operational aspects for the lifecycle of the cluster; abstract away the cloud specifics allowing us to focus on Kafka; achieve increased resilience and elasticity; implement automated Kafka rebalancing using CruiseControl, and harness all the metrics to implement an observable environment. We also plan to demo how these all come together. Join us as we share our team's learnings on: - Considerations for running a stateful service in a multi-tenant Kubernetes cluster: - Pod sizing in terms of memory and CPU - Scheduling - Persistent Volume Claims (PVC) tuning - Resiliency topics - How to handle regular Ethos upgrades and maintenance - How to bring custom monitoring solutions - Advanced network topics such as using dedicated VIPs If you or your team ever wanted to learn how to run your own stateful service in Kubernetes and/or see what's possible, come join us!

While all of the main cloud providers provide fully managed Redis services (Amazon ElastiCache, Azure Cache for Redis, and GCP Memorystore), it may also be simply implemented in Kubernetes if you require additional control over the Redis configurations. This session will lead you through setting up a Redis cluster on Kubernetes with data persistence. The lesson would concentrate on establishing a "prod"-ready Redis cluster that considers storage and persistence even after restarts and discusses recommended practices and considerations. With the help of monitoring and hardware optimizations for your cluster, you'll learn about measuring your performance and best practices for Redis on Kubernetes.

PV TrashCan - Protection against accidental deletion of PVs or Namespaces (DoK Day EU 2022) // Veda Talakad, Aditya Kulkarni & Aditya Dani 11:07

https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Accidental PVC delete or namespace delete can cause the Persistent Volume to get deleted. Such volumes lose their data and the stateful applications lose their state. By the use of Persistent Volume TrashCan, users can get a grace period to undo such unintended delete operation. The deleted Persistent Volumes are staged for delayed deletes. They continue to live even after being deleted from k8 perspective, for a configurable time(retention period) and based on the system’s usage. The storage class of the PVC can dictate if they need to be staged for a delayed delete. StorageClass can also allow for configurable retention period. To recover a deleted PersistentVolume, users can create a new namespace with the same name and reapply the original PVC spec. The PVC will reference a special StorageClass to indicate that the new PersistentVolume needs to be restored from the TrashCan. This will allow the application to restart with the right state and data. This talk will showcase how to overcome one of the admin’s pain point seen in field involving accidental deletions of PVCs by using advanced storage management solutions in Kubernetes. Veda Talakad is a Software professional with BS in electronics and communications mostly working in storage domain. Some of the professional areas of interests include scalability in distributed environment and cloud-native technologies for data management, Aditya Kulkarni: I have 10 years of experiance in Enterprise Data management.

This contract is a set of gRPC services for provisioning, utilizing, and snapshotting storage volumes. In this talk, we will focus on one aspect of the CSI spec: Volume Snapshots. The talk will cover volume snapshots on Kubernetes CSI, with a deep dive on Kubernetes CSI snapshots. A short demo on the basics of the CSI snapshots on Kubernetes will help show how easy it is to start using CSI snapshots. After covering the basics on both container schedulers, we’ll deep dive into how backup systems can programmatically interact with the Kubernetes CSI snapshots client. This example will be based on Stork, an open-source backup system that has implemented the CSI spec. I believe this talk will be beneficial to the community because it covers some storage-related topics that have not been covered much in previous conferences. I’m hoping to bring the unique perspective of a Kubernetes CSI and Nomad CSI contributor, while also covering the CSI plugin maintainer and end-user perspective. With this wide audience, many conference attendees will be able to learn about stateful applications, CSI volume snapshots, and developing CSI drivers for any container scheduler. Grant Griffiths is a core contributor and reviewer for the Kubernetes CSI and SIG Storage communities working at Portworx.

There are countless operator implementations available, and new operators are being released on a daily basis. Organizations managing hundreds of Kubernetes clusters for dozens of developer teams are also challenged to manage the lifecycle of hundreds of Kubernetes operators. The goal is to keep the operational overhead to a minimum. In this talk, a closer look into the lifecycle of operators will be presented. With an understanding of how operators evolve, it becomes clear what challenges during operator upgrades. A brief overview of lifecycle management tools such as Helm, OLM, and Carvel is presented in this context. In particular, it will be discussed whether these tools can help, which restrictions apply and where further development would be desirable. At the end of this talk, you will know what operator lifecycle management is about, what its challenges are, and which tools may be used to reduce operational friction.

People need to address various issues like resource isolation, queuing, and cost efficiency. This session will share details about those challenges and how to address them. We will also present a convenient (one-click) way to deploy Apache Spark on Kubernetes, and dramatically lower the barrier to use Spark. Bo has been working in big data area for 10 years, and gained intensive experience of running Apache Spark in large scale while he worked in in Uber.

https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Data doesn’t magically appear in our data centers. There are usually several phases and several storage locations along its journey throughout your organization. New architectural patterns, such as microservices, and new technology, such as Kubernetes are changing how we can think about and manage the large volumes of data coming at us. In this talk we will begin by quickly introducing the architecture and technology and how they make our lives better. From there it’s live demo time combining Java microservices, a processing caching service, a messaging layer, and a relational database all running in Kubernetes . This application will be handling frequently updated data, generating alerts on specific data events, and simultaneously populating a system of record. Come for the discussion, hands on demo, and witty banter! Steve is a Dad, Partner, Son, and Senior Developer Readiness Engineer for VMware Tanzu. In addition to showing off all the great work of the Tanzu team, he helps drive Tanzu developer experience. He can teach you about Containers, Kubernetes, Data Analysis, Java, Python, PostgreSQL, Microservices, and some JavaScript. He has deep subject area expertise in GIS/Spatial, Statistics, and Ecology. Before Tanzu, Steve was a developer Advocate for Crunchy Data, DigitalGlobe, Red Hat, LinkedIn, deCarta, and ESRI. Steve has a Ph.D. in Ecology and can easily be bribed with offers of bird watching or fly fishing. He has spoken at hundreds of conferences and done over 100 workshops including Monktoberfest, Red Hat Summit, MongoNY, JavaOne, FOSS4G, ODSC, AjaxWorld, GeoWeb, Where2.0, and OSCON.…
