Section #2 Cloud Deployment

Hi ! everyone on today we are going to learn about cloud deployment in short notes given below.

1. Cloud Deployment Models 

Public

The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organisation, or some combination of them. It exists on the premises of the cloud provider.

Security Challenges:

• Data breaches
• Data loss
• Account or traffic hijacking
• insecure interfaces
• malicious insiders

Control Challenges

• Elasticity control
• Service admission
• Data residency
• Performance monitoring
• Holistic management

Cost Challenges

• Loss of revenue (poor performance or availability)
• Workload sprawling
• Hidden costs (bandwidth, hard to forecast billing etc.)
• Business alignment

Private

The cloud infrastructure is provisioned for exclusive use by a single organisation comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organisation, a third party, or some combination of them, and it may exist on or off premises.

Community

The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises.

Hybrid

The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardised or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

Advantages:

• Ideal for fixed workloads
• Control, security, data sovereignty
• Elastic workloads
• Economics, speed, scale

Challenges :

• Loss of Security
  • Unsecure connection
  • Limited workload protection

• Soiled infrastructure
  • Inconsistent cloud architecture
  • Fragmented solutions solving networking security challenges
  • Different management tools

• Slow and Complex
• Require app re-configuration
• Slow and manual process of discovering infrastructure dependencies
• No visibility or control

2. Components of the Cisco Intercloud Solution

Describe the benefits of Cisco Intercloud

Cisco Intercloud Fabric for Business enables enterprises to create a seamless hybrid cloud by transparently extending their data centers or private clouds into public clouds and provider-hosted clouds. Using industry-leading Cisco networking capabilities, Cisco Intercloud Fabric allows enterprises to deploy a hybrid cloud that combines the benefits of public and private clouds. With Cisco Intercloud Fabric for Business, enterprises can have the agility and flexibility they need while retaining full security and control.

Describe Cisco Intercloud Fabric Services

Two Main Components:

1. Intercloud Fabric for Business (Data Center or Private Cloud)
   1. End User and IT Admin Portals
   2. Secure Fabric Extender Network, Compute, and Storage
2. Intercloud Fabric for Providers (Provider Clouds)
1. Intercloud Ecosystem
2. Cisco Powered Services and Cloud Providers
3. Windows Azure APIs
4. Amazon EC2 APIs

Self-service workload deployment: Cisco Intercloud Fabric allows end users to easily deploy workloads across various public clouds or migrate workloads across clouds. It offers a built-in administration and end-user portal as well as rich northbound APIs for automation.

End-to-end security: Cisco Intercloud Fabric provides end-to-end cryptographic secure connectivity from private to public clouds and security within the public cloud for data in motion.

Consistent networking capabilities: Cisco Intercloud Fabric provides Layer 2 network extension from private to public clouds, helping ensure application transparency. It includes integrated switching, routing, and virtual firewall and NAT capabilities.

Bidirectional workload mobility: Cisco Intercloud Fabric allows workloads to be migrated from private to public clouds and back. It includes automatic image conversion to the desired cloud format, so virtual machines can be placed on or migrated to any cloud.

Choice: Cisco Intercloud Fabric provides choice of cloud providers and hypervisors.

Architecture:

• Intercloud Director
  • web portal that is accessed by end uses or IT admins that controls the comments of Intercloud
• Intercloud Extender (Private Cloud) and Intercloud Switch (Public Cloud) creates a secure connection for communication
• Intercloud Provider Enablement Platform allows cloud providers outside of Amazon and Azure to integrate into Intercloud

Core Services:

• Networking – switching, routing, and other advanced network-based capabilities
• Security – VM to VM and App-to-App security controls
• VM Portability – VM format conversation and mobility
• Management and Visibility – private and hybrid cloud monitoring capabilities
• Automation and APIs – VM life-cycle capabilities, automated operations and programmatic APIs

Therefore, we have understood in this session about cloud deployment.
