1 Cloud Computing Today What You Need to Know Now Copyright 2013 Chappell & ssociates

2 n Organization without Cloud Computing Users Compute/Storage/Network pplication On-Premises Data Center Virtual Machine

3 Examining Cloud Computing Three categories Cloud pplications Commonly called Software as a Service (SaaS) Public Cloud Platforms Foundations for cloud applications and more Private Clouds Cloud platforms used by a single organization

4 n Organization using Cloud Computing Examples: Office 365, Dynamics CRM, etc. On-Premises Service Provider Users Cloud pplications (SaaS) Compute/Storage/Network Our focus Private Cloud Compute/Storage/Network Public Cloud Platform Compute/Storage/Network

5 Getting a New The traditional approach Request from administrator 1 3 Create on a specific server User 2 Verify that request is allowed dmin Management Tool Hypervisor Hypervisor Hypervisor

6 Getting a New Using Infrastructure as a Service (IaaS) User Self-Service Portal 1 2 Select image Create on some server IaaS Software Images Self-service s on demand Running on pooled hardware Hypervisor Hypervisor Hypervisor

7 EXTERNL PROVIDER ENTERPRISE Private Cloud, Public Cloud Self-Service Portal IaaS + More Lets you make your datacenter more efficient and effective User Private Cloud IaaS + More Public Cloud Lets you use external datacenters with massive scale and usage-based pricing

8 Private and Public Clouds Three truths Similar technology, different benefits Organizations want private and public clouds for different reasons Think and, not or Most organizations will use both private and public clouds Integration matters How an organization s private and public clouds work together is important

9 What Most Organizations Want Three goals Better datacenters Fewer datacenters Integration Private clouds More use of public cloud platforms Between private clouds and public clouds

10 Better Datacenters Private cloud scenarios Example: System Center 2012 Faster, simpler deployment of s in your own datacenters Faster, simpler deployment of applications with fewer errors utomated discovery and remediation of problems More...

11 Better Datacenters Evaluating private clouds Private Cloud Benefits Faster deployment of s and applications, because the process is automated Reduced administrative costs, because more of the process is automated Fewer deployment errors, due to automated deployment of standard services Easier cost management, with per- chargeback or showback Private Cloud Risks administrators find it hard to trust users to deploy their own s and applications administrators might resist having part of their job automated Defining standard services can be challenging, since users want different things Changing operational processes is hard for risk-averse IT departments

12 Fewer Datacenters Public cloud scenarios Example: Windows zure Faster, simpler deployment of s in external datacenters Giving developers an easily accessible and cheap dev/test environment Deployment of packaged and custom applications using pay-as-you-go computing resources Lower-cost storage More...

13 Fewer Datacenters Evaluating public cloud platforms Public Cloud Platform Benefits Faster deployment, because there s no need to wait for local computing resources Usage-based pricing, letting you pay only for what you use Reduced need for on-premises resources, such as servers and IT staff Easier upgrades, with no on-premises software to update Public Cloud Platform Risks Requires trusting a cloud provider for availability and data security Can raise legal/regulatory concerns with storing data outside the customer s premises Can be harder to integrate with existing on-premises applications Can have lower performance than onpremises applications nother worry: m I going to lose my job?

14 WINDOWS ZURE ENTERPRISE Integration Example: System Center 2012 and Windows zure IT dmin System Center Create s - Monitor applications - utomate Private Cloud - Create s - Monitor applications - utomate Windows zure Public Cloud

15 Cloud Computing Where should you start? Private clouds Public clouds Integration Deploying IaaS in your datacenter isn t technically difficult The goal is to automate wherever possible public cloud dev/test environment can bring immediate benefits with low risk Cloud storage can offer significant cost savings From the beginning, think about how you ll connect your public and private clouds
