Oracle Cloud Application Foundation What is needed for such a middleware PaaS service?

What is the minimal set of components needed to host SAAS-oriented applications effectively? •  a lightweight and standards-based Java server •  a Java framework, specifically designed for building cloud

applications •  an in-memory data grid for caching and clustering •  elasticity to adjust to workload variations •  integrated traffic management to route traffic throughout this

elastic infrastructure •  virtualization for optimal use of server resources •  simple provisioning – typically via self-service interfaces

HA with Side by Side Deployment Zero Application Downtime

•  Newer version of application deployed side-by-side with older version in same JVM

•  Clients already connected continued to be served by older version

•  New clients connect to newer version

•  Test versions before opening up to users

•  Rollback to previous versions

•  Automatic retirement – graceful or timeout

HA with Rolling Upgrade Zero Server Infrastructure Downtime

•  Upgrade a running cluster with a patch, maintenance pack or minor release without shutting down the entire cluster

•  During the rolling upgrade of a cluster, each server in the cluster is individually upgraded and restarted while the other servers in the cluster continue to host your application

•  You can also roll back the patch, maintenance pack, or minor release in a similar fashion

Application Server Scale Out Issues

•  Scaling cached data –  Difficult to scale clustered –  cached data reliably –  Consistency, expiry, location

•  Scaling state –  State is heavy and expensive –  Difficult to manage state

independent of application server

•  Scaling database transactions –  Difficult to buffer database

from spiky application layers yet maintain transactional integrity

Standard Two-Tier Weblogic Cluster Typical Two-tier WebLogic HA Cluster Architecture

•  Web Tier –  Servlet engines handle HTTP requests –  Sessions are replicated between Servlet engines

according to defined “replication groups” –  Servlets use replica-aware stubs to look up EJBs

in the Object Tier –  Primary/Replica pair are distributed according to

defined “replication groups” and order of precedence rules

•  Object Tier –  Object Tier provides EJB container services, JCA

adapters, JDBC, LDAP or other connectivity

Optimized Web Tier Dedicated session “grid” & session-less traffic processors

•  Engine Tier –  Engine Tier is “stateless” –  Optimized for request processing –  Engine Tier nodes may be added/removed with no

impact on ongoing sessions

•  Session Tier –  Stand-alone (POJO) Coherence nodes –  Zero code change for applications that use

standard WebLogic session replication or a plug-in solution from another vendor

–  Sessions are shared between all Web-tier instances, even different applications

–  Low memory/CPU overhead, fast startup –  Easily handles large sessions (10MB+) –  Optimized networking, serialization
