FAQs on our Cloud Computing Services

What is Cloud Computing?

Cloud computing is a type of computing in which IT- enabled services are delivered using internet technologies. Cloud computing leverages a network of remote servers, hosted via the internet, to store, manage and process data, rather than hosting it locally. Essentially, cloud computing is using someone else’s infrastructure and hardware to reduce the amount of capital investments your business needs to make.


Offerings under Cloud computing include a multitude of services like delivery of various types of IT assets as a service. this includes compute as a service, storage as a service, databases as a service, security as a service, backend as a service, etc.


Cloud computing makes reference to a 3-tiered architectural model – SaaS (software as a service), PaaS (platform as a service) and IaaS (infrastructure as a service). Service delivery is either from public cloud service providers or hosted internally or a private cloud.

What are the benefits of cloud computing?

Adoption of cloud has grown significantly in all type of industries as businesses see benefits in efficiency, cost savings, and performance with limited resources/budget. Organizations that have well-architected cloud computing models have achieved key business benefits including: faster deliveries, seamless data backup, enhanced productivity, scalability, reduced time, powerful server capabilities and flexibility.


Software product companies offering Software as a Service (SaaS) help customers in cutting down admin and operational costs that were part of the traditional models prevalent earlier.

Is cloud migration suitable for my business/enterprise application?

Having a cloud strategy is important for a contemporary business, especially in this digitally disruptive era. Without having a cloud strategy driven by business outcome, organizations increase the risk of failure and their investments may get wasted.


Organizations move or adopt cloud for various reasons. It is important to evaluate if cloud strategy and the existing IT landscape is beneficial for your organization’s growth. Before deciding on a cloud strategy, you should consider the following scenarios:


– What is the demand of IT throughout the year?


– How much of IT spend is impacting the company’s overall business?


– Are there better options available?


Such a detailed evaluation will give you the right vision to formulate an appropriate strategy that will help your organization. Businesses may also adopt a staggered approach for implementing a cloud strategy.

How to develop a cloud migration strategy?

Cloud strategy begins with a clear understanding of the organization’s technical and business objectives. The important drivers to shift to cloud and the solutions required to drive these changes are identified.


A proper cloud strategy road map is then developed to guide the cloud migration. The cloud adoption may be initiated on a small scale and as per the business or IT demands. Strategies driven from the needs also help choose the right cloud platform and execution.

What are the costs involved in cloud adoption?

Many assessment models and feasibility studies are available today that help in evaluating the TCO associated with successful cloud adoption. For some specific features, the cloud services may sound to be costlier than the standard value. However, the organization always has the option to scale down.


For some organizations, saving cost may be the primary business objective. A heterogenous approach to cloud adoption with visibility into TCO for Opex and Capex may be a more suitable for them.


Deciding a cloud services plan with acceptable pricing can be a bit challenging. Some cloud solution providers eliminate this worry by offering a flat rate pricing model. You can also decrease the cost factor by entering into a long-term Service Level Agreement (SLA) with your cloud provider.

Do I need a cloud migration strategy vendor or a cloud solutions partner?
The cloud migration strategy must be closely aligned to the business goals– short term as well as long term. A dedicated vendor or a cloud implementation partner will add value to the various cloud service options, ensure interoperability at multiple levels, and work on frameworks/details – which the internal teams may overlook/miss. Engaging a cloud service provider ensures that decisions are taken faster and there is clear accountability for tasks, especially during a crisis.
Is Cloud storage less secure an option than on-premise Data Centres (DCs)?
It is often perceived that cloud computing is more prone to security risks, when compared to on-premise data centres. The truth is that cloud service providers follow the most stringent security practices for cloud storage and hence, are faced with very few security breaches. Today, many live production commercial transactions are running on the cloud. In fact, more breaches have been recorded on on-premise DCs.
How do we prepare for a cloud migration?

Having a clear cloud strategy helps. It is best to have a clear idea about critical resources that need to go on the cloud. It is advisable to partner with a reliable cloud computing service provider, who can handle the transition with minimal disruption to service and business.


There are a few factors such as reliable network, data backup plan, etc. that one must be prepared with before migrating to the cloud, in order to avoid any critical data loss.

What workloads can I move to the cloud?

Workloads can be moved to the cloud depending on the business objectives and cloud strategy. Organizations may choose to move the complete IT workloads to the cloud, stepwise.


Conventionally, Cloud services were always used for data backup, but now it is extensively used for storing & processing application-based workloads like CRM, HR, marketing, etc.


Test and Dev environments can be quickly spun up in the cloud on demand, and after use, the service can be shut down. Scalable and on-demand applications work best in cloud as organizations don’t have to invest upright on capex. Backup as a Service helps in ensuring business continuity and reducing downtime.

What security parameters are generally part of the cloud?

Protection of business-critical resources against cyberthreats is one of the topmost concerns shared by organizations in the context of cloud migration. Cloud computing service providers implement numerous security features to secure the data, and also to ensure that the data is restored with minimum or no disruption.


Some of the key components of cloud storage security are encryption, identity management, application security, physical security, and firewalls. Cloud also provides appropriate Identity management, Access Controls, Authentication and authorization for access. With these security practices in place, organizations can ensure the safety of their critical data.

Is cloud safe for personal data and sensitive data?

Some of the key characteristics of a cloud computing model are the following:


  • Elasticity and Scalability
  • Self-service provisioning and automatic de-provisioning
  • Standardized interfaces
  • Billing self service based usage model
What are the basic characteristics of cloud computing?

Some of the key characteristics of a cloud computing model are the following:


  • Self-service provisioning and automatic de-provisioning
  • Standardized interfaces
  • Scalability and elasticity
  • Ubiquitous Network
  • Availability and Resilience
  • Billing on self-service based usage
What is the difference between elasticity and scalability in cloud computing?

In cloud computing, scalability refers to the process of statically increasing (scale up) or decreasing (scale down) the computing resources or its capacity to meet the varying workload requirements.


On the other hand, elasticity in cloud computing refers to commissioning and decommissioning of a large amount of resource capacity to meet the workload requirements. The underlying aim of cloud elasticity is to prevent overprovisioning or underprovisioning of a specific application/service.

What are the different layers in cloud computing?

The different layers of cloud computing are:


  • SaaS or Software as a Service (SaaS) includes any cloud-based application that can accessed over internet/web browser without having to download anything on the user’s device.
  • IaaS: IaaS: Infrastructure as a service offers the infrastructure and resources required to compute, store and network over the internet on a pay-as-you-go basis.
  • PaaS: Platform as a service offers the users with a complete platform( middleware, database systems, servers, storage, development & BI tools) to develop, deploy , and manage their application on pay-as-you-go basis. PaaS model eliminates the need to develop and manage infrastructure required to build the application.
What is the use of open source software infrastructure in cloud computing?
An Open source software infrastructure brings in various benefits and added flexibility to cloud computing ecosystem. This includes the flexibility to transfer cloud application across environments ( containers, data centres, servers) and platforms , universal developer workflows, seamless and rapid prototyping while aciliating business to build their own DCs ( data centre) in a private cloud environment.
How does virtualized platform help in implementing cloud solutions?

Virtual platform helps in:


  • Implementing Cloud OS
  • Dynamic workload placement
  • Isolating User and backend level concepts
  • Faster provisioning
  • Managing service level policies
What are the key factors one must consider before going for a specific cloud computing platform?

Before selecting any cloud computing platform, following factors must be evaluated:


  • Compliance with Industry Standards and certifications
  • Strategy to manage data loss/ latency
  • Data Governance and security plan
  • Data storage plan
  • Business continuity Plan
  • System Uptime
  • Data integrity in cloud computing
What is a private cloud?

A private cloud imitates the delivery models of public cloud providers. However, this is done completely within the firewalls for the benefit of the company’s users. A private cloud is heavily virtualized, and it consolidates a large amount of IT infrastructure into one/multiple logical resource pools.


Private clouds are owned and managed by individual companies. The access to the cloud may be limited to the enterprise that implements it or a part of its value chain.

Is it possible to migrate applications between cloud platforms?
Yes, but that doesn’t mean it will be easy. Certain services are used to move applications from one cloud platform to another (such as from AWS to Azure) and from internal data centers to the cloud. Cloud vendors adopt standards-based technologies in order to ensure true interoperability.
What is the significance of using APIs in cloud services?
APIs (Application Programming Interfaces) are used in cloud platforms because they:  
  • Facilitate communication between one or more applications
  • Act as gateways for enabling direct/indirect cloud software and infrastructure services to users
  • Save development effort and time
