In this talk, we will see concepts and recently architectural modification and news regarding the hybrid Cloud. An hybrid Cloud combines public cloud and private data center principles, granting access to the advantages of both kind of deployment. This is fast growing market, because many companies desire configurations and features from both the sides of the Cloud (regardless of their size and the number of users). We will talk about how customers are able to plan hybrid scenarios starting from on-premises deployment or from the Cloud, and then manage, control and secure both the environments with the same tools and interfaces. We will examine how workloads and users can be moved to the public Cloud and back to the private Cloud in a seamless manner and draw some considerations on this specific computing scenario.

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. Exchange Hybrid Deployment

11. Backup and Restore Data

12. Organizations With a Hybrid Cloud

13. Cloud Management

14. Cloud Management Platforms

15. 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

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 that’s 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
reliable…one day. Today, it is not. And until that day comes we
have the hybrid cloud”
“In the end, customers and users don’t even care about the
cloud, they just have a job to do. It’s performance and
convenience that an all-or-nothing cloud approach can’t deliver.”
