    Ten steps methodology for designing superior Cloud Native RESTFul Microservices APIs

    In most of the Monolithic applications business objects and data, model designs are already present. As part of moving to cloud, companies miss out of the use-cases the REST APIs need to support. Implementing cloud solutions on top of existing models may lead to performance issues with APIs and cause scalability issues. Clients need to rewrite code due to a new version of APIs.

     

    In this talk, we will explore ten steps methodology for designing superior Cloud Native RESTFul Microservices APIs. Firstly, define the business domain objects and how they relate to use cases. If the use-case is to support <500 ms response time and availability of 99.99%, design the application for Consistency, Availability, and Partition tolerant. Next, Create an ideal design which solves the use-cases, refer to the industry standard JSONs and designs from schema.orgiana.org, and ​microformats.org. Later, find the fail points in the process and go back to the first step to resolving the pain points: Go back to Define the problem. Question to ask is what can go wrong? When can it go wrong? Next, create Facade pattern to connect to either existing Monolithic App or create a new App to support the new cloud use-cases. Create API Gateway, so other companies can build software and create more offerings. Next, design common Layers for error handling, logs, and security. For API security, perform Threat Modeling to find security vulnerabilities and plan for mitigation of risks. Use generic authentication using SAML, OAuth, and JWT to support Authentication and Authorization. Next, create API Versioning strategy so that the REST API can evolve with minimal client changes. Apply Cloud Native design patterns for Resiliency. In the end, test APIs using contract driven testing and PACT files.

  • Have you ever wanted to deploy hundreds if not thousands of virtual servers with the single click of a button. Who hasn't? With a little JSON and the utility Terraform by HashiCorp, this power can be yours. 

    By deploying your infrastructure as a service, you can not only keep track of what resources are where, but also easily adjust or deploy additional resources without the need for navigating cumbersome user interfaces.

  • Java Modules are the future. However, our enterprise applications have legacy code, a lots of it. How in the world do we migrate from the old to the new? What are the primary challenges?

    In this presentation we will start with an introduction to modules and learn how to create them. Then we will dive into the differences between unnamed modules, automatic modules, and explicit modules. After that we will discuss some key limitations of modules, things that may surprise your developers if they're not aware of. Finally we will discuss how to migrate current applications to use modules.

To do this, we leverage our own natural language processing (NLP) and machine learning (ML) capabilities to provide a personalized and accurate search experience that delivers actionable answers to every question, instead of a simple list of links.

     

  • While "DevOps" is a very overrated and misused marketing term, we have many DevOps stories from around the world proving that shared responsibility between Dev and Ops can work out really well.

    A key component of DevOps is open communication and feedback loops. Monitoring data is one source of these feedback loops. Too often, however, this is only done in Operations for firefighting and root cause analysis. Kevin will discuss approaches of Shifting-Left Performance into the Continuous Delivery Pipeline to give earlier and faster performance, scalability and architectural feedback to developers, testers, architects and business.

    The presentation will include some hands-on experience on how to bake monitoring into DevOps tool chains such as JIRA, Bitbucket, Jenkins, Git, HipChat, JMeter, … - there should be something for everyone who wants to learn some new tips & tricks on how to become more “DevOps’y”
