Take your CMS to the cloud to lighten the load Brett Pollak Campus Web Office UC San Diego
Campus Web Office
About the CMS Qualifying academic & administrative units can host and maintain their websites with us
Manage over 140 websites in the CMS
Support over 900 CMS users
Redundancy at UCOP CMS database replicated each day to UCOP Webservers replicating constantly …Not the best solution…
What is cloud computing? Cloud computing is a style of computing where… Scalable and elastic IT-related capabilities are made available through Internet technologies.
Cloud Models Saas (Software as a service) You are provided with access to application software. You don't have to worry about the installation, setup and running of the application. Service provider will do that for you. You just have to pay and use it through some client. IaaS (Infrastructure as a service) Provides you the computing infrastructure, physical or virtual machines and other resources like virtual-machine disk image library, block and file-based storage, firewalls, load balancers, IP addresses, virtual local area networks etc. PaaS (Platform as a service) Provides you computing platforms which typically includes operating system, programming language execution environment, database, web server etc.
What is “outsourced” to the cloud?
Advantages of cloud computing In principal the cloud offers shared resources to provide economies of scale Cloud does not require the purchase and maintenance of physical hardware Cloud can provide elasticity to peak load capacity to accommodate spikes in traffic (first day of classes) Cloud can provide failover through the use of availability zones Cloud can provide the ability to easily spin up environments for testing, training, or temporary needs
Deployment Models Private cloud: Is a single-tenant environment where the hardware, storage and network are dedicated to a single client or company. Public cloud: A multi-tenant environment, where you buy a “server slice” in a cloud computing environment that is shared with a number of other clients or tenants.
Hybrid Cloud On-premise datacenter resources are connected to a public cloud service We created a Virtual Private Cloud (VPC) environment in AWS VPC is an extension of our on-premise datacenter
Amazon Virtual Private Cloud (VPC) Let’s you provision a logically isolated section of the AWS cloud You define the IP Space Subnets Hardware VPN
Amazon Virtual Private Cloud (VPC) Possible to connect multiple VPC’s together
ACT’s Hybrid Cloud
Amazon Direct Connect Additional way to connect your private cloud to AWS VPC Allows for higher bandwidth connectivity VPN typically caps out at 4Gbps Direct Connect offers 10Gbps $$
Why is the CMS a good fit for the Cloud? The service is relatively stand-alone… Vendor supported application Not reliant on downstream data feeds Few integration points
Why take the CMS to the cloud?
Elasticity for predicted peak load times
Elasticity for unpredicted situations
Elasticity for unpredicted peak load times
Factors that play into cost Number of Amazon servers needed to handle your web site traffic The bandwidth consumed by your application, and Which database or storage options your application uses.
CMS costs with AWS Monthly compute and bandwidth costs $1,100 per month
Next steps: ACT’s Hybrid Cloud VMs for recharge 3 departments in pilot phase Full recharge service expected in ‘15
