Agenda

3. From IDC, July 2013
The 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

23. Cloud Service
A resource container possessing a URL attribute
for addressing VMs in the service
Availability Set
A group of VMs in different fault domains to
ensure redundancy
Affinity Group
Provides higher degree of proximity within
datacenters
Basic Azure Terminology
Platform 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.
