Serverless has been a hot topic for quite a while, but we are still in the early stages when it comes to best practices and tooling. Justin Donohoo, Co-Founder of observian.com, gives us the pros and cons of 4 architectural patterns that he calls: “Microservice / nano pattern”, “Service Pattern”, “Monolithic Pattern” and the “GraphQL Patterns”. Besides these patterns we also learn about common cost traps and how to “architecture around them”. For more information on serverless Justin also shared his recent Serverless Meetup presentation. And stay tuned – there will be more from Justin around secrets, containers and anything else there is to know about cloud native applications.* https://twitter.com/justindonohoo* https://www.observian.com/* https://docs.google.com/presentation/d/1ffx9wWioFahxQJbhpPhJ3FC-csNXrdEGdufrj5LwV6w/edit#slide=id.p* https://observian.com/tools/secret-awsome/* https://www.puresec.io/blog

Chris Burrell, Head of Technology at Landbay, shares insights on navigating microservice architecture and contract-based testing with Swagger. He highlights the shift away from end-to-end testing to speed up continuous delivery while ensuring that code changes don’t disrupt interoperability. The conversation delves into the nuances of defining REST API contracts, maintaining backward compatibility, and the benefits of Swagger tools that streamline development processes. Burrell’s expertise illuminates how organizations can innovate while managing complex API ecosystems.

How can you get your build times down to minutes? Exactly: eliminate the largest time consumer! At Landbay, where Chris Burrell heads up technology, this was end-to-end testing.Landbay deploys their 40 different microservices into ECS on a continuous basis. The fastest deployment from code to production is 6 minutes. This includes a lot of testing – but simply not the traditional end-to-end testing any longer. Chris gives us insights in contract testing, mocked frontend testing, how they do Blue/Green deployments and what their strategy is when it comes to rollback or rollforward.For more information watch Chris’s talk on 6 minutes from Code Commit to Live at µCon and his lightening talk on CDC Testing is Dead – Long Live Swagger.https://twitter.com/ChrisBurrell7https://skillsmatter.com/skillscasts/10714-6-minutes-from-code-commit-to-live-you-won-t-believe-how-we-did-ithttps://skillsmatter.com/skillscasts/11147-lightning-talk-cdc-testing-is-dead-long-live-swagger#video

Have you heard about Load Shedding? If not then dive into this discussion with Acacio Cruz, Engineering Director at Google ( https://twitter.com/acaciocruz ). He walks us through what Google learnt from one of the early outages at Gmail and how he and his team are now applying concepts such as load shedding to avoid disruption of their services despite spikes of load or unpredictable requests. We also discuss SRE (Site Reliability Engineering), how it started and transformed at Google and how we should think about automation, configuration of automation, and automation of automation. For more details – including visuals – we encourage you to watch Acacio’s breakout session from devone.at on YouTube (Load Shedding at Google).https://devone.at/speakers/#acaciocruzhttps://www.youtube.com/watch?v=XNEIkivvaV4

Security is on everyone’s mind. One way to strengthen security of your software and increase the awareness of your engineers is running a Security Hackathon – or a “Bug Bounty Program”. We invited Pascal Schulz ( https://www.linkedin.com/in/pascalschulz/ ), Security Engineer at Dynatrace, to the show to give us more background on HACK.DT – a security hackathon he and his team ran earlier this year within the Dynatrace Engineering Labs. For additional details check out his blog Running a successful internal bug bounty program and ping him on twitter (@PascalSec) in case you have further questions.https://www.dynatrace.com/news/blog/running-a-successful-internal-bug-bounty-program/

We got to chat with Danilo Poccia (@danilop), Global Serverless Evangelist at Amazon Web Services, on how to best leverage serverless and its new principles to speed up bringing new features to the market. We learn about Event Driven Architectures, Continuous Deployment into Production leveraging Canary and Linear Deployments as well as how to automate testing when pushing your serverless code through CI/CD. Also – did you know that you can run all your Lambda tests locally in your machine? Check out AWS SAM ( https://docs.aws.amazon.com/lambda/latest/dg/serverless_app.html ) and SAM Local ( https://docs.aws.amazon.com/lambda/latest/dg/sam-cli-requirements.html ) for more information.Make sure to check out Danilo’s Serverless by Design website ( https://sbd.danilop.net/ ) where it you can visually create your end-to-end serverless architecture and get a CloudFormation template to stand up this environment in your AWS account.

Donovan Brown, Principal DevOps Manager at Microsoft, is back for a second episode on CI/CD & DevOps. We started our discussion around “The role of Monitoring in Continuous Delivery & DevOps” but soon transferred over to our recent most favorite topic “The Unbreakable Delivery Pipeline”. Listen in and learn more about how monitoring, monitoring as code and automated quality gates can give developers faster and more reliable feedback on the code changes they want to push into production.Also make sure to follow up on Donovan’s road show when he shows Java developers how to build an end-to-end delivery pipeline in 4 minutes. And lets all make sure to remind him about the promise he made during the podcast: Building a Dynatrace Integration into TFS and adopt the “Monitoring as Code” principle

15 Minutes of your day! That’s all it takes to make the first step towards applying DevOps best practices. To hear more about this and other suggestions on how to jump start your DevOps transformation tune into this episode where we chat with Donovan Brown ( http://donovanbrown.com/ ), Principal DevOps Manager at Microsoft.Did you know that over the last 7 years the VSTS team has increased deployment velocity from once every 3 years to once every 3 weeks? Coordinating 50 different feature team that all commit to master daily? If you always thought that transformation like this are only possible in smaller development organizations then be proven wrong by Donovan, a member of the League of Extraordinary Cloud DevOps Activists. If you want instant advice simply tweet using #LoECDA and summon “the league”!

Serverless comes with its own set of best practices, quirks and benefits when it comes to monitoring and performance engineering.In this episode we have Michael Garski, Director of Platform Engineering at Fender Musical Instruments ( https://www.linkedin.com/in/mgarski/ ), giving us a technical deep dive into lessons learned and best practices they learned when re-platforming their architecture to AWS Lambda. We get to learn about optimizing Cold Starts, Re-Using HTTP Connections, Leveraging API Gateway Caching and finding the sweet spot for CPU & Memory settings to optimize price/performance of AWS Lambda executions.For more details check out Michael’s slides on Innovating Through React Native Mobile Apps.

Josh Long ( https://twitter.com/starbuxman ), Developer Advocate at Pivotal, Java Champion and author of 5 books, gives us a great tour through the latest that is happening in the Spring Universe. If you are new to Spring check out http://start.spring.io/ and create your first project within minutes. When it comes to Reactive make sure to check out https://projectreactor.io/ and dive into https://micrometer.io/ to learn more about how to extract metrics from Spring applications. As Josh is constantly traveling the world chances are high you can meet him at a local conference.
