For every new customer free resources / month: •  750 hours of Amazon EC2 Linux Micro Instance •  10 GB of Amazon Elas:c Block Storage (EBS) •  5 GB of Amazon S3 storage •  30 GB per of internet data transfer -‐> use it for anything you like J The most comprehensive Oracle applications & technology content under one roof

3 Oracle in Public Clouds The most comprehensive Oracle applications & technology content under one roof

Oracle on AWS 1. Oracle AMIs on EC2 2. Oracle VM Templates on EC2 3. DIY AMIs The most comprehensive Oracle applications & technology content under one roof

1. Oracle AMIs for AWS http://aws.amazon.com/amis/Oracle The most comprehensive Oracle applications & technology content under one roof

Oracle AMIs Limita:ons •  Newest Oracle SW versions only •  WebLogic / SOA Suite images US region only •  Very few images in SE-‐Asia region •  Some images only 32-‐bit •  Most images S3 based -‐> not persistent The most comprehensive Oracle applications & technology content under one roof

2. Oracle VM Templates on EC2 •  Oracle VM and Amazon’s EC2 are both Xen based -‐> AWS now oﬀers Oracle VM based AMIs h^p://aws.amazon.com/solu:ons/global-‐solu:on-‐ providers/oracle/faqs/ Expecta:on: More up to date images, improved availability for diﬀerent regions The most comprehensive Oracle applications & technology content under one roof

Oracle VM Templates on EC2 The most comprehensive Oracle applications & technology content under one roof

Oracle VM Templates on EC2 •  Must use AWS console -‐> no Oracle VM Tooling -‐> No live migra:on •  Only High-‐Memory EC2 instances •  Oracle RAC not supported •  Oracle supplied AMIs only (no documented way to create your own AMI) •  US-‐East region only -‐> tech preview, not for wider usage The most comprehensive Oracle applications & technology content under one roof

3. Create your own AMI •  You can bring you license / buy new license •  Start with current OEL / RedHat / CentOS Linux version •  Start with EBS-‐based AMI •  Select if 64-‐bit Linux if appropriate •  Install the SW you need •  AUer conﬁgura:on -‐> Create a new AMI … The most comprehensive Oracle applications & technology content under one roof

Create your own OFM AMI The most comprehensive Oracle applications & technology content under one roof

4 Distributed OFM Installa:ons The most comprehensive Oracle applications & technology content under one roof

Clustering in the Cloud The most comprehensive Oracle applications & technology content under one roof

JNDI-‐Updates / Cluster Heartbeats •  There is no IP-‐mul:cast with AWS or Rackspace -‐> use WLS unicast serng instead (it‘s default, but less scalable) The most comprehensive Oracle applications & technology content under one roof

JMS Scalability / Availability Distributed Des:na:ons { Managed Server1 Distributed Des:naton Q JMS_Surf1 Service Managed Server2 Migra9on JNDI lookup(“UDD”) Q JMS_Surf2 Managed Server3 Q JMS_Surf3 Q Whole-‐Des:na:on returned Managed Server3 Server Q JMS_Surf3 Migra9on The most comprehensive Oracle applications & technology content under one roof

WebLogic JMS in the Cloud •  No ﬂoa:ng IPs in the Cloud -‐> No whole-‐server migra:on •  Use WebLogic service migra:on •  Automa:c service migra:on requires nodemanager -‐> JMS alterna0ve for applica0ons: Opt for AWS Simple Queue Service (SQS) The most comprehensive Oracle applications & technology content under one roof

Don’t forget: Cloud Management Scripted conﬁgura:on, monitoring, mul:-‐cloud support, server templates? •  Oracle Enterprise Manager •  Enstratus •  RightScale •  Group of server conﬁgs that can be cloned •  Mul:-‐cloud images The most comprehensive Oracle applications & technology content under one roof

5 Cloud Services The most comprehensive Oracle applications & technology content under one roof

AWS Auto Scaling •  Automa:cally adds or removes EC2 instances •  Based on low/high threshold –  CloudWatch metrics (EC2, RDS, SQS/SNS, RDS, …) –  own custom metrics •  Scheduled •  Fixed size / replace unhealthy instances •  SNS no:ﬁca:on aUer auto scaling The most comprehensive Oracle applications & technology content under one roof

Simple Queueing Service (SQS) •  Similar to JMS queues -‐> async & decoupling •  Zero installa:on, oﬀ-‐instance, WS-‐API •  1 to one communica:on •  At least once seman:c •  Message automa:cally persisted in store -‐> No HA conﬁgura:on necessary The most comprehensive Oracle applications & technology content under one roof

Simple No:ﬁca:on Service (SNS) •  Similar to JMS topics •  1 to one many communica:on •  best-‐eﬀort seman:cs •  Supports following messaging formats –  HTTP(S) using POST –  Email –  Email with JSON format –  SQS The most comprehensive Oracle applications & technology content under one roof

SQS vs. WebLogic JMS Queues The most comprehensive Oracle applications & technology content under one roof

SNS/SQS or JMS? SQS/SNS : •  Similar in func:on •  Zero installa:on, but AWS only •  Less parameters (ACK mode, compr., ﬂow ctrl, …) •  No HA conﬁgura:on necessary •  Unlimited, managed, reliable persistent store •  APIs but no JMS interface •  Free usage :er -‐> alterna:ve for applica:ons The most comprehensive Oracle applications & technology content under one roof

Storage/DB Design Alterna:ves •  S3 large, sta:c objects •  EBS persistent storage (DB data ﬁle) •  RDS DB as a Service (MySQL/Oracle) •  local transient storage •  Cloud Front content distribu:on network •  Simple DB simple data, indexing, query The most comprehensive Oracle applications & technology content under one roof

Launch DB Wizard for Oracle Database The most comprehensive Oracle applications & technology content under one roof

AWS Rela:onal Database Service Features: •  Oﬀ-‐Instance •  Zero installa:on •  Resizable instance running MySQL/ Oracle DB •  Mul:-‐Availability Zone instances with failover •  Read replicas •  Backup window and automated backups •  Minor patches and version upgrade •  No support for APEX The most comprehensive Oracle applications & technology content under one roof

RDS or Custom AMI? RDS is the be^er solu:on if •  You need a DB quickly •  You don’t have much DB or cloud knowledge •  You don’t want to hire an DBA •  What you care is the JDBC-‐URL to connect Note: Calculate the monthly/yearly costs!

Cloud Load Balancing (LB) •  You can’t move your HW LB into the cloud •  SW based LB (HAProxy, WLS proxy plugin): virtualiza:on bo^leneck > 100.000 pck/s •  Amazon’s ELB = LB as a Service •  ELB is oﬀ-‐instance, scales itself by adding IPs The most comprehensive Oracle applications & technology content under one roof

AWS Elas:c Load Balancer as a Service The most comprehensive Oracle applications & technology content under one roof

6 conclusion The most comprehensive Oracle applications & technology content under one roof

Conclusion •  OFM is ready for the cloud •  There is a learning curve involved •  Cloud services cannot replace clustering / HA setup for JMS for Oracle products (OSB etc.) •  Oracle’s public cloud oﬀering can be improved •  Clouds are there.
