An Overview

Cloud Platform Technologies

What “Cloud” Means Two different things

Applications and computing resources running in an external datacenter with usage-based pricing

‒ Examples: Office 365, Google Apps

‒ Example: Windows Azure, Amazon Web Services

Any offering that provides Infrastructure as a Service (IaaS)

‒ Example: Windows Azure, Amazon Web Services

‒ Example: System Center 2012, VMware vCloud

Lets you make your datacenter more efficient and effective

Lets you use external datacenters with massive scale and usage-based pricing

Using a Public Cloud Platform Segmenting the market

Independent software vendors (ISVs)

Need a platform for creating SaaS applications

Might want a platform for extending current on-premises applications with cloud components

Enterprises

Want to run current applications at lower cost

Want a platform for building new applications (employee-facing or customer-facing)

Public Cloud Platform Technologies

The most important today:

‒ Computing

Infrastructure as a Service (IaaS)

Platform as a Service (PaaS)

‒ Storage

Relational storage

NoSQL storage

Blobs

There are many more

‒ Messaging, identity, caching, …

Computing Infrastructure as a Service (IaaS)

Users create virtual machines (VMs) on demand

‒ From a library of VM images

Strengths:

‒ Familiar technologies supporting many scenarios

‒ Limited code lock-in

‒ Can control and configure environment

Weaknesses:

‒ Must control and configure environment

‒ Requires administrative skills to use

Computing Platform as a Service (PaaS)

Developers provide an application, which the platform runs

‒ They don’t directly create VMs

Strengths:

‒ Provides higher-level services than IaaS

‒ Requires essentially no administrative skills

Weaknesses:

‒ Allows less control of the environment

‒ Supports fewer scenarios

An Aside: Scenarios for IaaS and PaaS Why IaaS is more popular than PaaS

IaaS PaaS

Moving existing applications to the public cloud Yes Maybe

Yes Deploying packaged applications No

General-purpose VMs on demand, e.g., for dev/test Yes No

New applications Yes Yes

Disaster recovery Yes No

Yes Running a standard relational DBMS, e.g., SQL Server No

Storage Relational

Managed (PaaS) relational storage in the cloud

‒ With support for SQL

Strengths:

‒ Familiar technologies

‒ Many available tools, e.g., for reporting

‒ Limited data lock-in

Weaknesses:

‒ Performance can vary

‒ Scaling to handle very large data is challenging

Storage NoSQL

A broad category of managed (PaaS) non-relational storage technologies

Strengths:

‒ Scaling to handle very large data can be straightforward

‒ Can be cheaper than relational storage

Weaknesses:

‒ Unfamiliar technologies

‒ Few available tools

‒ Significant data lock-in

Storage Blobs

Storage for Binary Large OBjects in the cloud

‒ Such as video, back-ups, etc.

Strengths:

‒ Globally accessible way to store and access large data

‒ Can be cheaper than on-premises storage

Weaknesses:

‒ Provides only simple unstructured storage

Cloud Platform Software

Cloud Platform Service

Cloud Service or Cloud Software? Understanding the alternatives

Cloud platform service

‒ A hardware/software combination

‒ Typically provided by organizations that run Internet-scale services (e.g., Microsoft and Amazon)

They write their own software

Cloud platform software

‒ Provided by software vendors (e.g., VMware and Microsoft) and open source projects (e.g., OpenStack)

‒ Hosters can use this software to offer a public cloud service

The same software can also be used in private clouds

VMware Cloud Foundry Essentials

Cloud Foundry is an open source PaaS platform

‒ Led by VMware

Designed to support diverse technologies:

‒ Frameworks: Spring, Rails, etc.

‒ Storage: MySQL, MongoDB, etc.

VMware provides a public dev/test service

‒ Partners provide commercial offerings

Eucalyptus Essentials

Eucalyptus is essentially an on-premises implementation of parts of AWS

‒ Including EC2 and S3

It provides management tools that can be used with:

‒ The on-premises Eucalyptus cloud

‒ AWS

Using Eucalyptus with AWS allows creating a consistent private/public cloud

OpenStack Essentials

OpenStack is open source software for an IaaS cloud platform

‒ Original technology based on work by Rackspace and NASA

‒ Many more participants today

Aimed at both private and public cloud platforms

OpenStack-based offerings today include:

‒ Rackspace Cloud Hosting

‒ HP Cloud Services

The Public Cloud IaaS World A broader look

Public IaaS service is widely available

Other IaaS providers today include:

‒ Terremark

‒ Savvis

‒ IBM

‒ Oracle

‒ GoGrid

‒ Lots more . . .

The Public Cloud PaaS World A broader look

Public PaaS service is broadly available today

‒ It’s a complicated, rapidly evolving market

‒ The services offered by PaaS vendors vary widely

There’s still disagreement on what “PaaS” actually means

There is no clear PaaS leader

‒ PaaS hasn’t yet caught on in a big way

Conclusions

Public cloud platforms are important

‒ Many vendors are active here

Public and private clouds are connected

‒ Many organizations will use both

This is everybody’s next big platform decision
