1.Hybrid Clouds: Silver Bullet of the Cloud Computing?

2. From Gartner Symposium/ITxpo 2013 October 21-24 in Goa, India The use of cloud computing is growing, and by 2016 this growth will increase to become the bulk of new IT spend, according to Gartner, Inc. 2016 will be a defining year for cloud as private cloud begins to give way to hybrid cloud, and nearly half of large enterprises will have hybrid cloud deployments by the end of 2017 The basic issues have moved from what is cloud to how will cloud projects evolve 3. Public vs Enterprise Clouds 2014 Red Hat Summit: Building enterprise clouds: Resetting expectations to get them right Public Clouds Enterprise (Private) Clouds Simple Complex Cheap-ish Expensive Self service Self-service Standardize and fully automated Low standardization and automation Elastic (application level) All but elastic Resource consumption-based Mostly unmetered Infinitely scalable (infrastructure level) Capacity constrained Minimally governed Heavily governed 4. Introducing the Hybrid Cloud 5. What is a Hybrid Cloud? Hybrid cloud (or hybrid IT) is the result of combining internal and external services, usually from a combination of internal and public clouds. Hybrid cloud models can be implemented in a number of ways: o Separate cloud providers to provide both private and public services as an integrated service o A single cloud provider offering a complete hybrid package o Companies with a private clouds integrate a public cloud service into their infrastructure 6. Who is in Control about the Cloud Private cloud usually is where a CIO - Chief information officer has control, the public cloud is usually governed by CEO - Chief executive officer and the outsourcing is often reserved to the CFO - Chief financial officer 7. The Eight Different IT Environments Bilderbeek consulting defined some years ago eight different IT environments that will coexist in the foreseeable future Four homogenous environments : Private Cloud Public Cloud Legacy IT Outsourcing Four hybrid environments: Hybrid Cloud Hybrid Hosting Hybrid Operations Hybrid Architecture 8. Managing the Cloud 9. Hybrid Infrastructures Hybrid clouds combine private infrastructure and operations with shared infrastructure and operations Hybrid hosting combines private and shared infrastructure within a shared, outsourced operations environment Hybrid operations combine private and shared operations Hybrid architecture combines private legacy IT such as client/server with private on-demand IT such as private cloud 10.

Why You Need a Cloud Management Platform Many enterprises have a multi-cloud environments using many different providers, which creates a complicated IT environment. Cloud management platforms (CMPs) adds a management layer to create a private, virtual private, public, o hybrid cloud environment 16. CMP Players (Infotech Research Group) 17. Management Tools and Automation 18. System Center VMM Virtual Machines can be deployed on-premise, in a private cloud, or in a public cloud like Windows Azure through the use of System Center Virtual Machine Manager (VMM) and System Center App Controller 19. Monitoring 20. Hybrid Cloud Challenges and Benefits 21. Hybrid Cloud Pain Points Since hybrid clouds typically involve a mix of technologies and vendors, we have an increasing level of complexity Companies are facing complications including: IT transformation Cloud Security Connection Speed and Avaialability 22. Hosting and Cloud Study 2014 Hosting and Cloud Go Mainstream 23. IT Organizations as Brokers of IT Services Internal IT staffs (which have typically worked in an on-premises data center) can view cloud computing as an outsourcing career threat IT organizations must serve as the intermediary between their internal customers and all IT services (whether internal or external). IT organizations can offer the same Price Capacity Speed of the external cloud, maintaining Security Governance Reducing IT service costs 24. Hybrid Cloud Security Because each enterprise splits up its data between public and private clouds in a unique way, data security methods must solve multiple challenges, securing: On-premise data center resources Applications migrating to the public cloud Data stored with multiple cloud service providers Mobile devices which connect to the cloud infrastructure 25. Split Key Encryption Each data object (such as a disk or file) is encrypted with a unique key that is split in two The first part the master key is common to all data objects in the application and remains to application owner The second part is different for each data object and is stored by the Key Management Service Every time the application accesses the data store, both parts of the key are used to dynamically encrypt and decrypt the data 26. ExpressRoute ExpressRoute is an Azure service that enables you to create private connections between Azure datacenters and infrastructure thats on your premises or in a colocation environment ExpressRoute connections do not go over the public Internet, and offer higher security, more reliability, faster speeds and lower latencies than typical connections over the Internet 27. ExpressRoute Connectivity Options There are two connectivity options for ExpressRoute: Direct Layer 3 connectivity through an Exchange Provider Layer 3 connectivity through a network service provider 28. Benefits of the Hybrid Cloud We can try, now, to list some points that could drive the adoption of the hybrid cloud Data placement for regulatory compliance Higher performances and availability for mobile users Costs (fees of a cloud service are sometimes higher than the costs of an on-premises infrastructure) 29. The Embarrassing Truth About The Hybrid Cloud (Gene Marks Forbes) The cloud will be wondrous and fast and secure and reliableone day. Today, it is not. And until that day comes we have the hybrid cloud In the end, customers and users dont even care about the cloud, they just have a job to do. Its performance and convenience that an all-or-nothing cloud approach cant deliver.
