  1. 1. Delivering Hybrid Cloud Solutions with KEMP LoadMaster and Microsoft Azure Layer 7 Application Delivery in the Microsoft Azure Cloud New York: 631-345-5292 • Limerick: +353-61-260-101 • Hannover: +49-511-367393-0 • Singapore: +65-62222429
  2. 2. Why expand your IT platform to Hybrid Cloud? What benefits does the Microsoft Azure platform provide? How to achieve high availability with the KEMP Virtual LoadMaster for Azure? What are the key features and benefits of the KEMP Virtual Loadmaster? Agenda
  3. 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.
