Solaris 11 for DevelopersWebinar Series

4Oracle Corporation

Objectives of this Presentation

• Share ideas to – architect a Solaris

development system– lower costs by smart

consolidation– react faster on changing

requirements– make SW developers

more productive– simplify internal

processes

• Turn technologies like ZFS, Zones, Crossbow into time saving solutions

Decision Tree for Lab SetupCategory Logical Domains Solaris Zones

Concept Full OS replication with hypervisor

Isolation and virtualization of APIs and services

HW resources assigned Assignment optional; shared with global zone

Resource mgmt. HW resources assigned

Optional (RBAC, zones, proj.)

Instance life time long (static) as needed (very dynamic)

Memory overhead

of a full OS... of a few daemons

Limitations Same shared kernel Focus:* Flexibility* Agility* Features

6Oracle Corporation

Challenges Faced by Development and QA Engineers

• Hardware resources are very limited

• Multiple test environments are required to deploy different software stacks

• Considerable amount of time required to install the OS and configure resources to test environments

• Restoring test environments repeatedly after regular testing due to changes while testing

7Oracle Corporation

Logical Domains (LDom)

• LDom provides virtualization based on the hypervisor

• LDom provides provides protection and isolation through SPARC hardware and hypervisor firmware

• Each virtual machine (logical domain) appears as an independent machine

• Each domain is a virtual machine with reconfigurable subset of machine resources and its own independent OS

• LDom is now known as Oracle VM Server for SPARC

8Oracle Corporation

Oracle Solaris Zones

• … provide a partitioning technology

• … are available on Oracle Solaris 10 and Oracle Solaris 11

• … isolate software applications and services by using software defined boundaries (based on Solaris kernel)

• … enable private execution environments within a single instance of the Solaris kernel

• … provide a virtualized Solaris OS image, including a unique root file system and a shared set of system executables, libraries and resources

9Oracle Corporation

Zone-Based Virtual Test Environments

• A local zone can be an ideal test environment

• Each local zone appears as an independent, isolated test system

• You can easily setup zone-based test environments

• You can establish separate test environments in different zones, for different applications, all within the same system

• You can easily restore and clone zones-based test environments

• The virtual environment guarantees sufficient CPU and memory resource allocation to applications while retaining the ability to use idle resources as required

10Oracle Corporation

ZFS

ZonesSolaris 11

TCP/IP

• Isolation• Minimal overhead• Organizational

independence• No license issues• Solaris 10 and Solaris

11 support (in a Solaris 11 system)

• Ease of application configuration through VNICs

• Complex internal network topologies

• Organizational independence

• Cloning on demand• Deduplication on demand• Snap shot on demand• Compression on demand

Solaris 11

Development

Environments

1+1+1 is greater than 3Things coming together in Solaris 11

11Oracle Corporation

Scenario 1: Application Support for Solaris 10 and Solaris 11

• Goal: Build cost efficient applications which support customer installations of the last ~8 years and the next 3 years– Support Oracle Solaris 10 and Oracle Solaris 11– Build on Solaris 10 and qualify for Solaris 10 and 11– Use the latest compiler (Sun Studio 12.3)

• Strategy: Use one Oracle Solaris 11 system and exploit the Solaris 10 infrastructure as well as the Solaris 11 infrastructure– Retire old, slow, energy inefficient V- and E-class servers and

consolidate on T4 servers

12Oracle Corporation

Scenario 1: The Architecture

• Solaris 11 Global Zone– Compiler and tools• Sharing through NFS

– General infrastructure– Version management• IPS• Highest version recommended

• Solaris 10 Zone (Build Server)– Solaris 10 SVR4 packages as

needed– General infrastructure imported

through NFS mounts– Version management• SVR4• Studio implicitly maintained

through IPS

13Oracle Corporation

Scenario 1: Comments

• Solaris 10 Branded zones require – an existing Solaris 10 image (Administration Guide) to be cloned– or a bootable Image to be attached– This is the way to upgrade and consolidate your build servers... :-)

• The cross mounts require NFS as sharing technology– LOFS mounts will not work for multiple mount points

• Solaris 10 patching will have to happen individually

14Oracle Corporation

Scenario 2: QA requires Developer to analyze Problem

• Solution:– Provide

independent copy of setup

– Use zones cloning to create a copy of the application (disk) state and Solaris zone

– Provide a live zone on demand for the developer

15Oracle Corporation

Scenario 2: How to get it done...

• Setup QA Env. in a zone

• Shutdown QA zone when needed

• Clone zone– Have template with system

configuration

• Restart QA zone

• Boot debug clone on demand

• Destroy debug clone zone when needed

• Impact– Disk: Minimal, zone clones

share unmodified disk blocks

– Memory: Extra application memory needed for parallel work. Halted zones don't need memory

– CPU: as needed

• Privileges required– Zones admin on target sys.– Access to IP addresses for

remote access (or use global zone as gateway)

• Resources: – Get Started creating zones

16Oracle Corporation

Scenario 3: Qualifying Applications for Solaris 10 and Solaris 11

• Option: Parallel QA– CPU, Memory, network

requirements will double– ...but not more than double!

• Option: Alternate QA– The halted zone will require disk

space for non deduplicated content

– Shutdown or reboot within seconds• Comment

– Solaris 11 zone can be patched in sync. with global zone

17Oracle Corporation

Scenario 4: QA in Complex Network Topologies

• Concept– Configure internal network– Keep network topology as private

network– Keep traffic inside the system

• Benefits– Load tests without side effects to

lab net– Test “network plumbing” of

application installation software– Configure multiple network

configurations (no costs as long as the zones are being shutdown)

18Oracle Corporation

Scenario 4: Comments

• Comments– New: Network Administration has been completely refurbished!– New: Virtual NICs allow applications to hard code against vnics

without knowledge of the physical interface!– Network Resource control is optional (… and recommended)

• Simulate extreme customer network configurations

19Oracle Corporation

Scenario 4: References

• References– Solaris 11 Network Virtualization Technology– How to Script … Network-In-a-Box– Oracle Solaris 11 … Network Virtualization and … Management

20Oracle Corporation

Example: “Eat you own Dog Food” Oracle Remote Solaris Lab

• A secure cloud environment built on Solaris 11 technologies– Use of Solaris network virtualization technologies to create a secure

VLAN per user and segregate network traffic– Zones technology segregates partner VMs– Secure Global Desktop provides segregated communications

channels– ZFS technology provides rapid deployment of images in partner

VMs and secures data

21Oracle Corporation

Example: “Eat you own Dog Food”Oracle Remote Solaris Lab

• An easy to use self-service secure cloud environment for testing

– Provides partner access to SPARC and x86 VMs in Oracle Solaris 11 environments

– Simplified cloud deployment can be up and running in minutes

– Self explanatory web UI reduces start up time to almost zero

– Partner can make use of Virtual Machine Images with software packages preinstalled (such as Sun Studio Compilers, Oracle Data Base, WebLogic) to create tailor made VMs
