Description:
If you are thinking of a PaaS then you need to consider some important features and understand how to think about the different vendors. There are literally hundreds of PaaS vendors. Why? It's a very important and powerful step in improving time to market and costs for software development. Issues like Resource Sharing, Hybrid, Polyglot, Security, HA / DR, Ecosystem PaaS, Lifecycle management, DevOps vs PaaS, different IaaS Vendors migrating into PaaS services, Autoscaling, Open Source vs Proprietary, Performance Management, Operations

PaaS is “aaS” for Services and Applications Development (see blog below)

• Low Initial Cost to Deploy• Incremental Cost as you use or develop more• Automated Deployment• Management Built-In• Best Practices baked in• Self-Service• Lifecycle Managed• Reuse• Resource Sharing

Roles for PaaS

• Super-Tenant (and related roles)– Configures and manages operations across subtenants and

applications during the entire lifecycle– Defines the lifecycle

• Tenant– Can build, integrate, test, deploy versions of applications or

services• User

– Uses an application (may not be aware that a PaaS exists)

What’s the difference DevOps/PaaS?

DevOps – DIY automation

• Use Chef, Puppet• You write the rules• You script deployment• No auto Scaling • You do FT/HA strategy• Tenant management

and other tasks like security may be very manual still

PaaS – its built in

• Continuous deployment • Multiple clouds

simultaneously• Auto-scales / Load

Balances• Self-service Automation• Gives you a dashboard• May not work with your

tools or processes

There are many different types of PaaS

• Application PaaS – Force.com• Infrastructure Tied PaaS - Azure• Development Environment Tied PaaS –

Openshift, mPaaS, iPaaS, BPMaaS, APIMaaS, …• Generic PaaS – CloudFoundry, Apache

Stratos(WSO2 Private PaaS)• Ecosystem PaaS – Heroku, WSO2 App Factory,

Force• DevOps PaaS – CloudFoundry, OpenShift, Stratos,

Page 12: Choosing a dev ops paas platform svccd presentation v2 for slideshare

Another PaaS Taxonomy

• Vendor Tied PaaS – could be one application, one development environment, one operating system, one IaaS, one virtualization technology

• Functional PaaS – oriented around one developmental function such as iPaaS, BPMaaS, APIMaaS

• Hybrid PaaS – support for more than one IaaS environment

• Polyglot PaaS – support for more than one development environment

• Ecosystem PaaS – Support for full lifecycle including development environment and store

Why so many PaaS?Bottom Line: Faster Time to Market

Before - software development is costly, risky and slow process• Do tests on early versions of software to determine loads from

customers• Plan demand expectation and hardware required• Acquire hardware and networking equipment for a time period

including additional hardware for failures and expected peak periods• Find space for hardware, plan network integration plan, rule

changes in switches, routers, update configuration management, outages for upgrades and changes

• Test hardware and network with software to insure it works• Understand failure modes, when to scale, runbooks for different

scenarios, train people in operation and what to do in different scenarios. Write scripts to detect scenarios and provide needed information in failures.

• Write or acquire management tools, put in instrumentation in hardware.

• Plan for upgrade strategies, outages and SLA measurements, backup policies.

• Beta customers • Go Live

Now – cheaper, faster, less risky • Choose IaaS vendor• Choose PaaS platform• Write some runbooks for different scenarios,

train people in PaaS operation• Deploy software• Beta customers• Go live

Entry Points for PaaS

• Inside Organization– DevOps automation– Cloud Busting– Resource Sharing– Enterprise Refactoring and Renewal

• Outside Organization– SaaS application development– External API service development– PaaS for partners/customers

I’m going to talk about Polyglot Hybrid Generic PaaS’s

YES

• Polyglot Hybrid PaaS• Ecosystem PaaS

NO

• Competitive landscape• Application PaaS’s• Vendor PaaS’s• Functional PaaS’s

Enterprise Issues to be discussed

PH PaaS

• Private or Public• Hybrid Cloud Capability• Resource Sharing differences• Security Concerns• High Availability• Polyglot• Management and Performance

Monitoring• Automated Resource Allocation• Scaling Automatically• Operations Support• Pluggability• Multi-tenancy of applications and

users

Ecosystem PaaS = PH PaaS +

• Multi-Environment support

• Business Process Automation

• Lifecycle support• Social Capabilities• Store• Reuse

Page 18: Choosing a dev ops paas platform svccd presentation v2 for slideshare

Private or Public

Private / Run yourself• More flexibility to use

hybrid capabilities, customize for your development

• Gain Experience yourself before launching into public sphere

Public• Start cheap and small• Running a PaaS isn’t

trivial• Possibly locked in to a

vendor and its problems and limitations on performance and scale, compliance, security …

Page 19: Choosing a dev ops paas platform svccd presentation v2 for slideshare

Hybrid Capability Has been deemed Important which is why we see some possibly misusing the term

• Change cloud vendors based on:– Security – Cost – Zone Coverage– Performance Problems– Vendor instability– Or any reason that may occur

• Use Multiple Clouds – Have on premise hardware as well as public – Burst on demand– Run certain services in some clouds that perform better– Run some tenants in some regions on different clouds– Run production, test, demo, staging … in different clouds

Some Vendors claim Hybrid meaning: not different types of clouds. Seriously restricts choices

Public IaaS Vendors – large variabilityHigh Risk – not all PaaS’s run on all IaaS10:1 price / performance or more

Dell*, Azure**• Microsoft (Free)• Dell - On-premise like

Joyent**, SoftLayer*• High Performance

– Joyent special virtualization, SmartOS

– Softlayer – bare metal• MongoDB, Hadoop

Rackspace*, HP*• MySQL• OpenStack Pioneer

Google**

• Google Compute Cloud• Google App Cloud

Amazon AWS**• Wide variety of choices• Lots of extra value

services• Poorest performance • Highest cost

*OpenStack ** Proprietary

Private IaaS Choices

VMWare – expensive

Eucalyptus(AWS) – ties you to Amazon

OpenStack– Many supporters

Cloudstack

OpenNebula

You die and go to Heaven in the CloudHeaven is a PaaS

You ask at the gates: Is Heaven PaaS a Hybrid PaaS?

Saint Peter Responds: No, there isOnly one Heaven and you will find it perfect

You’re a little skeptical but you nod and ask: Is Heaven a Polyglot PaaS

Saint Peter responds: No, everybody in Heaven speaks the same language

You ask: Does Heaven have multi-level multi-tenant isolation?

Saint Peter is clearly getting annoyed and Disturbed at the direction of your questions:We have no secrets here in Heaven.

Finally you ask: Does Heaven have multi-tenant component sharing?

Saint Peter: Look boy, you are looking for hell.There they have many different hells, they allSpeak in tongues and everybody is a whore.

Resource Sharing is Critical Performance Issue

Dedicated InstancesGreat Performance but expensive!Multi-tenancy

Allows each instanceTo be shared – betterutilization

Break into componentsAllows each piece to be utilizedAnd split to different servers Giving higher performance

Multiple copies ofEach componentAllows unlimited scale

Individual components can be scaled independentlyGiving maximum utilization and scalability as well as Fastest response to load changes

Tear down Instances fasterAnd easier too

Dedicated instances expensive But scales

High Availability / Disaster Recovery

HA

• Is the PaaS itself fault tolerant?

• Fault tolerant technologies for all supplied cartridges?

• Active/Passive and Active/Active deployments supported?

• Load Balancing between fault tolerant components?

• Single points of failure anywhere in the system?

DR

• Does the PaaS include a gReg to replicate governance data between regions?

• Does the PaaS support artifact distribution automatically to all regions?

• Does the PaaS support resource backup?

Page 26: Choosing a dev ops paas platform svccd presentation v2 for slideshare

© WSO2 2014

Security built-in?

Authentication

• Federated Identity support including OPENID, SAML and dual factor auth?

• Support for multiple LDAPs or at least one LDAP per tenant?

• Is the IM scalable to support your needs?

Authorization, Audit

• Does the PaaS support OAUTH2, XACML and other authentication standards?

• Does it scale to your needs?

• Can you audit the logs or easily build alerts to detect potential break-ins or fraud?

Page 27: Choosing a dev ops paas platform svccd presentation v2 for slideshare

Auto Scaling

Metrics

– Most use http queue length

Or do you need:

– CEP real time events – use any metric or load, application log or data

How Automatic

• Is the scaling manual? • Does it do automatic up AND down • Can you set rules• by tenant• different clouds• time of day or by region depending

on the load in that region?• Can you scale individual cartridges

or only whole applications?• Can you scale resources as well as

CPU, i.e. # of nodes in cassandra for instance

Open Source or Proprietary?

• Private PaaS Open Source is the only way (in my opinion)

• Public PaaS • in general will probably not be open source•Won’t be as flexible

Page 30: Choosing a dev ops paas platform svccd presentation v2 for slideshare

© WSO2 2014

Performance Management?

Management Capabilities

• Does the system come with integrated BAM or other performance management?

• Does it allow 3rd party monitoring to be added?

• Does the system check internal and external performance?

Visualization and Escalations

• Do you get good visualization tools

• Is the monitoring flexible• Can the system detect

anomalous situations and instantiate a workflow

• Can the system perform automatic workarounds to known events or scenarios?

Page 31: Choosing a dev ops paas platform svccd presentation v2 for slideshare

© WSO2 2014

PaaS Management

• Do all parts of the PaaS have APIs?• Do all parts have CLI interfaces?• Does the PaaS have consistent operation for all parts?• Is there a flexible enough billing and accounting

component?• Is the security component flexible enough to meet

your growing needs?

Page 32: Choosing a dev ops paas platform svccd presentation v2 for slideshare

Upgrades? Down Times

• What are the components to be upgraded and can they all be upgraded without any or very little interruption?

• What modules will require down time or maintenance?

• Are downtimes required for data backup or other maintenance?

Page 33: Choosing a dev ops paas platform svccd presentation v2 for slideshare

© WSO2 2014

Management Data / BigData

Integrated

• Is bigdata and CEP integrated with the system

• Can it be used for both PaaS purposes and application purposes?

• Can column stores be allocation automatically for applications or tenants?

Ready

• Is the PaaS instrumented?

• Can the system log data from applications as well as the PaaS to be used for analyzing tenant usage

Page 34: Choosing a dev ops paas platform svccd presentation v2 for slideshare

© WSO2 2014

Multi-Tenancy

• Multi-tenancy means isolation of data and process– Can you isolate at the

hardware level– Can you isolate at the

container level– Can you isolate at the

cartridge level– Can you isolate at the OS level

• Can you isolate by role or group– Application development

tenants– Application user tenants– Supertenants

• Examples:

– Different tenants can be on different physical machines located in different regions of the world

– Different tenants can be allocated isolated private instances of cartridges or containers

– Application developers can be isolated from production users

Ecosystem PaaS

Page 37: Choosing a dev ops paas platform svccd presentation v2 for slideshare

© WSO2 2014

Ecosystem PaaS

Become a leader in your Ecosystem

• Provide your customers with complete development environment

• Share your APIs, Applications

• Allow them to share their APIs and Applications

• Provide quality control of end products and usage

Ecosystem Examples

• Boeing – Make Buying Boeing Aircraft

easier to operate in a best practices way

– Allow tighter integration of Boeing, Airline and Support Vendors

• Force.com– Make integration with

Salesforce easier

• Heroku– Make development easier

Page 38: Choosing a dev ops paas platform svccd presentation v2 for slideshare

© WSO2 2014

What is an Ecosystem PaaS?

• Full Lifecycle support for tenants to develop their own services, mobile applications or web applications– including source code repository, agile project management,

automated build, continuous integration, continuous deployment for each tenant and tenant application

• Governance– Decide who can see or share or run what services, mobile

applications, source code, what approval for promotion, how many resources each tenant can use, service tiers, track usage of each tenant of the PaaS or any of the services in the PaaS

• A social Store to share entities– APIs, mobile applications or web applications between

tenants, promote collaboration

Tenant Administration?

Creating / Assigning Tenants

• Assign tenants resources in different locations / clouds

• Tenant LDAP / security policies supported?

• Different tenant tshirt sizes supported?

Administration of tenants

• Tenant size migration• Tenant instance migration• Tenant backup• Tenant isolation• tenant SLAs and

performance• Tenant logs• Tenant billing• Tenant support with easy

problem reporting and documentation, chat

Page 43: Choosing a dev ops paas platform svccd presentation v2 for slideshare

© WSO2 2014

Application Lifecycle Management

No Lifecycle support

• The devOps will have more manual elements more room for error and less consistency

• You are using tools that cannot be integrated into your DevOps Platform?

• You aren’t requiring promote standard processes in development?

• You don’t have requirements for automated governance of development products

Lifecycle support

• Controls and Policies • Standardize on tools like

Maven, Jenkins, Agile project management, Git?

• Do you have both automated tasks to perform as part of promotion and human involvement and approval?
