Serverless Architectures and VMware Dispatch Framework (BAW3)

Now I am by no way an expert with Serverless Architectures, but I saw an announcement from VMware the other day about VMware releasing the Dispatch Framework, and I thought that I would investigate a little further.

Having utilised servers as the main part of my career to date, the idea of a ‘Serverless’ environment seems a little strange.  Here is my brief crash course in ‘Serverless Architectures’:

  • Serverless architectures refer to applications that significantly depend on third-party services or code that is run in ephemeral containers
  • These are known as Backend-as-a-service or Function-as-a-service
  • Backend-as-a-service refers more to applications that significantly or fully depend on 3rd party applications / services (‘in the cloud’) to manage server-side logic and state.  These are typically ‘rich-client’ applications (like mobile apps) that use the vast ecosystem of cloud accessible databases, authentication services etc.
  • Function-as-a-service is more to do with applications where some amount of server-side logic is still written by the application developer but unlike traditional architectures, is run in stateless compute containers that are event-triggered, ephemeral and fully managed by a 3rd party.  AWS Lambda is one of the most popular implementations of Function-as-a-service

This therefore brings us onto the announcement by VMware of Dispatch, an Open Source Serverless Framework.

This was first announced during VMWorld 2017 with an early demo but the team behind the framework have been working to define what a VMware-based serverless framework would look like.

Dispatch is built on Kubernetes and provides tools and services to deploy and manage production-ready, function-backed serverless applications.

Dispatch is available as an Apache 2.0 open source project.  The feature set is limited in this early release but you can bet that VMware will be developing this heavily moving forward.  Below is a diagram showing the architecture for Dispatch.

Blog-a-Week 2018 Posting (BAW):

In previous years, I have had periods throughout the year where I have been unable to post an entry to my blog.  During 2018, my aim is to post a blog entry each week of the year.  I’m hoping that the blog entries will all be useful bits of information or items that I’ve been working on recently but if the standard of the entries drops, I apologise now, as this could have been a busy week and I wasn’t able to put in as much time as I would have liked into the post
