The Cloud: a new era of utility computing All types of computing are available as a service via global network
• Applications: Business Applications … Software as a Service (SaaS)
• Platform: Databases and Middleware as a Service (PaaS) • Infrastructure: VM, OS, Servers and Storage as a Service
(IaaS)

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

29
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
