Architecture

Cloud computing architecture is made of several layers. This helps in achieving greater operational efficiency.

• Cloud controller or CLC: Helps to manage virtualized resources like servers, network and storage.
• Walrus: Helps as a storage controller to manage the demands of the users.
• Cluster Controller (CC): Helps to manage the virtual networking between Virtual machines and external users.
• Storage Controller (SC): Helps the block-form storage device, dynamically attached by Virtual machines.
• Node Controller (NC): Helps as a hypervisor and controls the VMs activities such as execution, management and termination of many instances


PLANNING
Cloud computing has changed the way global businesses work. It is now taken as 'cheaper, better and faster' accelerator of business innovation, efficiency and service to customers. Planning for a Cloud deployment calls for complete assessment of the business needs.
• Identify the applications and data that need to be deployed
• Assess the benefits and risks associated with these deployments
• Weigh the costs involved, direct (like usage charges) and indirect (like potential breach of data)

The four factors of planning a Cloud deployment are,
Security:
Data security becomes very crucial when dealing with sensitive and classified information. Proper legal compliance by Cloud providers ensures dual benefits of data security and economical way to use the Cloud.

Performance:
This brings us to identifying applications that need to be deployed on Cloud. This has an impact on each application' performance. It is always better to check the cloud-based application performance under typical and peak conditions.

Integration:
This becomes a challenge when dealing with disparate applications, and ensures their working together seamlessly. Our Cloud integration experts work with third party teams to pay attention to APIs (application programming interfaces), and ensure how well the disparate applications can be integrated.

Compliance: It is understood that different types of data are subject to different compliance initiatives. While choosing the third party Cloud, we ensure that our client' data is safe and secure, and the data security compliance norms are duly met by the third party provider.

DESIGNING
A good Cloud design calls for proactive planning that includes, not guessing your capacity, testing systems at production scale, automating design changes, adhere to evolutionary design and not rapid changes, and have clarity on your application needs.

DEPLOYMENT
The choice of the Cloud deployment model is based on where the infrastructure for deployment resides and controls over the infrastructure. A Cloud deployment model should serve should meet different organizational needs. Your knowledge of the business environment, value proposition and costs associated helps you to make an informed decision. User experience and control over it is the key factor that influences your choice of Cloud model. In a Private Cloud you have complete control over user's experience. In Public Cloud there are no controls. The client's legacy applications need to be adapted or migrated to modern languages and APIs. This will help them to interact with other applications regardless of where they are deployed.

MONITORING
Monitoring is very essential to make sure Cloud services are working properly. Cloud monitoring process includes evaluating, monitoring, and managing cloud based services, applications and infrastructure. Vysra Information Technologies monitors different types of Cloud services
• SaaS – Services like Office 365, Salesforce and others
• PaaS – Developer friendly services like SQL databases, caching, storage and more
• IaaS – Servers hosted by cloud providers like Azure, AWS, Digital Ocean, and others
• FaaS – New serverless applications like AWS Lambda and Azure Functions
• Application Hosting – Services like Azure App Services, Heroku, etc
Choosing the right application performance monitoring (APM) solution can be challenging. Herein comes our experience and expertise in providing the right-fit Cloud monitoring tools and providing a continuous monitoring strategy.

MANAGEMENT
The objective of Cloud management is to ensure that all the cloud computing-based resources are working optimally and properly interacting with users. The management of Cloud includes,
• Performance monitoring (response times, latency, up-time, etc.)
• Security and compliance auditing and management
• Initiating and overseeing disaster recovery and contingency plans
With Cloud computing turning complex, with wide variety of private, hybrid, and public cloud-based systems in use, the Cloud management tools should be as flexible and scalable as its cloud computing strategy.
