Virtualization
Virtualization helps an organization to create pools for its compute resources that can be encapsulated and assigned to applications and services required by different departments according to their resource requirement. This type of encapsulation makes compute infrastructures more flexible, prevents under-utilization of resources and increases the overall reliability of the infrastructure
The key IT infrastructure domains being virtualized are:

Servers
Firms use server virtualization to consolidate infrastructure and application software onto fewer, more powerful machines. Server virtualization has become increasingly popular, though mostly on x86 systems.
Server Virtualization gives
Flexible workload management
Basic high-availability and disaster recovery services
Rapid server migration and consolidation

Storage
Virtualized storage allows you to create a dynamic pool of storage capacity regardless of the physical location of the disk or the type of media used. The most basic form of storage virtualization is the Redundant Array of Inexpensive Disks (RAID), which is at the core of just about every disk-based storage system.

Storage Virtualization gives:
Simplified management
Improved utilization
Painless migration
High-end features often found on expensive arrays

Networks
Virtualization allows network administrators to operate multiple devices in the network as a single asset and manage the use of network resources more efficiently.
Network Virtualization provides
Removing potential bottlenecks
Simplifying network design and management
Giving the network a services orientation

End user clients
Virtualization on the client focuses primarily on simplifying the client’s software management and securing sensitive applications.
End user virtualization gives
Manageability
Migration
Instant access
Security

Sify’s Virtualization Services offerings
Sify Virtualization Group (SVG) helps customers to derive greater value from their resource investments. Sify can deliver a cost effective solutions in virtualization design, integration and deployment in an onsite – offshore model.

Sify offers Virtualization across all domains mentioned here. The Virtualization management stack here explains all the different management layers of Virtualization.

Services Offered
Discovery and Proof of Concept
Before Virtualization of your IT infrastructure, the Sify Virtualization Group (SVG) conducts a pilot program at your premises. SVG will do the initial evaluation and discovery, design the lab setup and show the proof of concept.

Evaluation and assessment
The Sify SVG can help a customer evaluate virtualization of infrastructure resources (either with or without the discovery phase) by conducting the following:

• Identification of assets for virtualization
• Evaluation of the constraints (both technical and business)
• A Complete inventory of applications
• Understanding the utilization and geographical constraints with respect to the infrastructure

Quantitative analysis

• Preparing the consolidation strategy and a space analysis on the infrastructure.
• Hardware Analysis
• Justification of the cost and Return on Investment

Compatibility Analysis
Configuration Analysis
Space consolidation
Hardware consolidation
Software (licenses) consolidation

Application profiling and consolidation

• Application consolidation
• Shared Application Infrastructure

Security

• Best practices
• Security audit
• Access control compatibility

Project Planning
Once the evaluation is complete, Sify can help in the project planning through design, deployment, migration and disaster recovery of the customer’s IT resources.

Design
Sify can help in design the following

• Datacenter design
• SAN design
• Storage Virtualization
• Network design
• Network Virtualization
• DR design
• HA design
• Network design
• Service consolidation

Implementation
Once planning and designing is complete, Sify can help in implementing the solution.

Performance services
The crux of virtualization is in the performance of the virtualized servers, storage and networks. Sify can help in optimizing and improving the plans in the overall implementation.
