In this session, we will build a minimum viable Spring Data web service with REST API, add a MySQL backing service as the primary data store, and a Redis Labs backing service for caching. We will demonstrate performance metrics without Redis caching enabled and then with Redis caching enabled. I will also provide an intro-level explanation of the platform capabilities within Pivotal Web Services.

3. What are we talking about today?
! Spring Data Redis
! Spring Boot
! We’re going to build a Spring Boot web service with MySQL storage
! Add in Redis caching with Spring Data Redis
! Deploy to the cloud! (Cloud Foundry)
! Stream metrics and compare caching vs. no caching

4. But first…
A database joke

5. Why did the database have problems
ingesting data?

6. Because it had ACID indigestion

7. Ok let’s get serious
Let’s talk about architecture

8. Microservices & Polyglot Persistence
If you’re into that kind of thing

10. Spring Data Redis
10

11. What is Spring Data Redis?
! Easy access to Redis from your Spring applications
! Provides a variety of abstractions for you to interact with Redis
• Spring Data Repositories (NEW!)
• RedisTemplate
• CacheManager
! Available as a Spring Boot starter project from http://start.spring.io
! Provides a CacheManager implementation so you can use annotation-
driven caching on methods

14. Spring Boot
A JVM micro-framework for building microservices

supports rapid
development of
production-ready
applications and services

29. Deploy to the cloud!
Using Cloud Foundry
29

30. Cloud Foundry
! Open-source platform as a service (PaaS)
! Supports multiple cloud providers
! Supports build packs for multiple application
frameworks
! Supports Linux container deployments
using Diego
! Supports Docker container registries
30

31. Application Server vs Linux Container deployments
31

32. Application Server Deployment
! Load balancing requires
provisioning of new VMs and app
server installations
! Poor resource isolation; memory
leaks can cause other
applications to become
unavailable
! Runtime environment is driven by
the operator
32
Virtual Machine
App
Linux Kernel

Hardware Infrastructure

33. Linux Container Deployment
! Development team drives the
application runtime of a container
! Containers are resource isolated,
allowing efficient scheduling onto
a grid of VMs
! Containers take seconds to start,
VMs take minutes
! It’s not a rule that there is one
microservice per container

34. Microservices - Container Deployment
! Each microservice can be containerized with their application dependencies
! Containers get scheduled on virtual machines with an allotted resource
policy
34

35. Auto-scaling
! Minutes to start a VM, but seconds to start a container
! An elastic runtime handles auto-scaling of VMs with cloud providers
