Agenda

From IDC, July 2013The Cloud Opportunity: Global Momentum Takes Hold Public IT cloud services spending will reach $98 billion in 2016, with a compound annual growth rate (CAGR 2011- 2016) five (5) times the growth of the IT industry overall.

Early-stage companies (less than five years in business) are the most eager buyers of cloud, concerned with start-up capital costs and less likely to build and staff a conventional datacenter, and plan to increase their spend on public cloud by 24% over the next few years.

Applications

Azure VPN

VLM-Azure for Application Microsoft to Azure IaaS

Directory Replication

Problem• Limited datacenter capacity• Slow response to changing business and capacity needs• Requirement for on premise cost reduction• Need for minimal development efforts to transition apps

Solution• Azure provides a way to transition Tier 2/3 apps to cloud-hosted

VMs freeing on premise resources• Internal/External client access remains unchanged• KEMP’s VLM delivers unified experience in public/private cloud• VLM’s full Layer 7 load balancing, content switching and reverse

proxy services minimizes required application augmentation

Cloud Service for Application VMs (optional)

Client requests name resolution to access the service or application

DNS entry for Service or application endpoint (URL i.e. cloud.kempdemo.com) is delegated to LoadMaster GEO

LoadMaster uses GEO functionality to determine the health status of each participating LoadMaster and Virtual Service

Client receives response with service IP to connect to

Client application connects to resolved IP address

VLM forwards the request to the application servers according to the configured load balancing mechanism and server’s health state

Affinity GroupProvides higher degree of proximity within datacenters

Basic Azure TerminologyPlatform as a Service (PaaS)Services platform for applications with low infrastructure maintenance. Lowers administration and provides easily scalable environment for websites and services. No need to worry about patching, backing up, HA, etc.

Infrastructure as a Service (IaaS)VMs on demand created from available images and requiring same administration as on premise virtual infrastructure. Gives greater flexibility.
