Cloud Definitions

Cloud Definitions
§ Infrastructure as a Service (IaaS) : Virtual hardware (VMs, Storage, DNS,
load balancers, VLANs, VPN etc.)
§ Platform as a Service (PaaS) : Environments (VM + OS + DB, VM + OS +
App Server etc.)
§ Software as a Service (SaaS): Applications delivered over the cloud.
§ Database as a Service (DBaaS)
§ Bring Your Own License (BYOL)
§ On-Demand License

Pricing?
§ Comparing prices can be difficult.
§ vCPUs, memory, disk space, network traffic.
§ Price-per-min/hour. Reserved period of time (1-3 years) may give a
heavily discounted price.
§ Licensing : On-Demand or BYOL.
§ High Availability (HA) costs extra.

Oracle Licensing
§ For certified cloud providers (Oracle, AWS, Microsoft Azure)
§ So
§ AWS: 16 vCores = 8 Physical Cores * 0.5 = 4 Core licenses.
§ Azure: 8 vCores = 8 Physical Cores * 0.5 = 4 Core licenses.
§ Physical: 8 Physical cores (Intel) * 0.5 = 4 Core licenses.

Oracle
Databases on the Cloud

Amazon Web Services (AWS)
§ Elastic Compute Cloud (EC2):
§ IaaS - Virtual Machine (VM).
§ Self-managed.
§ BYOL.
§ Relational Data Services (RDS) for Oracle :
§ DBaaS.
§ No OS system administration and tooling to greatly reduce DBA work.
§ BYOL or On-Demand Licensing.
§ Some functionality restricted or prevented entirely, as is typical of many
DBaaS offerings.
§ RDS offerings for MySQL, MS SQL Server, Postgres etc.

Microsoft Azure
§ No DBaaS for Oracle databases.
§ IaaS - Virtual Machine (VM).
§ Self-managed.
§ BYOL.
§ Certified and supported for Oracle Linux and RHEL.

Oracle Cloud
§ Database Schema Service:
§ 5-50G schema.
§ Data access using RESTful web services, not SQL*Net.
§ Virtual Image:
§ Virtual Machine (VM) with Oracle software zips.
§ Create DBs using DBCA
§ Data access using SQL*Net.
§ DBaaS:
§ Similar to Virtual Image, but also includes cloud-based tooling.
§ DBaaS - Managed (Not Yet Available):
§ A fully Oracle managed version of DBaaS.

VMware vCloud Air
§ Hybrid Cloud.
§ Interesting for existing VMware shops.
§ Seamless move from on premise to cloud.
§ Currently not a certified or supported cloud provider for Oracle.

Quick Tips

Silent Installations
§ Get used to doing silent installations!
§ Build a response file on a client using the OUI.
$ ./runInstaller -record -destinationFile /tmp/10gR2.rsp

§ Get used to doing silent installations!
§ Build a response file on a client using the OUI.
$ ./runInstaller -record -destinationFile /tmp/10gR2.rsp
§ Use the response file on the server.
$ ./runInstaller -silent -ignoreSysPrereqs -responseFile /tmp/12cR1.rsp
§ Relying on remote X emulation is a nightmare!

Command Line DBCA
§ Get used to using the command line DBCA!
$ dbca -silent -createDatabase
-templateName General_Purpose.dbc
-gdbname cdb1 -sid cdb1 -responseFile NO_VALUE
-characterSet AL32UTF8
-sysPassword OraPasswd1
-systemPassword OraPasswd1
-createAsContainerDatabase true
-numberOfPDBs 1
-pdbName pdb1
-pdbAdminPassword OraPasswd1
-databaseType MULTIPURPOSE
-automaticMemoryManagement false
-storageType FS
-ignorePreReqs
§ Or use a response file.
§ Relying on remote X emulation is a nightmare!

Encrypt Database Connections
§ Use Native Network Encryption to protect connections.
§ Just add the following to the server’s sqlnet.ora file.
SQLNET.ENCRYPTION_SERVER=REQUIRED
SQLNET.ENCRYPTION_TYPES_SERVER=(AES256)
§ Or use TCP/IP with SSL/TLS.
§ The internet is not safe without encryption!

Concerns

Concerns
§ Legal Jurisdiction.
§ Security.
§ Governance.
§ Network Latency : App Server, DB links, ETL.
§ Traffic Costs : Some cloud services charge for network usage.
§ Transfer Technology : Are SQL*Net, SSH, FTP allowed?
§ Migration : How do you get your data there?
§ Total Cost of Ownership (TCO) : Hard to determine.

Oracle Database on the Cloud?
§ It depends!
§ Should be a case-by-case judgement.
§ Unlikely that a one-size-fits-all policy will work.
