What Is Cloud Computing?

Cloud computing entails storing, accessing, and processing data and applications over the internet rather than on local servers or personal devices. Leading technology giants like Microsoft Azure, Amazon Web Services, and Google Cloud provide on-demand access to vast computing power, storage, and an array of services via the cloud.

Simply put, cloud computing allows you to access IT resources and capabilities located in robust data centers via the internet. This eliminates the need for expensive on-site servers or hardware. With cloud computing, you pay only for the computing resources you use, similar to how you pay for electricity or water.

Cloud service providers own massive data centers around the world, housing thousands of powerful servers along with networking and storage infrastructure. Everything is highly redundant to ensure maximum uptime and availability. Organizations can leverage these resources via the internet to deploy applications, store data, test ideas or expand capacity on-demand.

Cloud computing is immensely scalable, allowing you to provision more resources when needed. It is also highly reliable, with built-in backup systems and disaster recovery capabilities. Migrating to the cloud transfers the burden of managing infrastructure and application delivery to experts like Microsoft, AWS and Google.

Key Advantages of Cloud Computing

Cloud computing offers organizations from startups to the Fortune 500 a wide array of benefits that can enhance efficiency, spur innovation and cut costs.

Lower Costs

Cloud computing eliminates the substantial upfront costs associated with building on-site data centers and buying hardware, like servers, routers, backup systems and cooling equipment. Instead, you pay on a flexible, as-needed basis for the computing resources used via the cloud. This leads to significant cost reductions versus traditional on-premises IT infrastructure.

With cloud computing, organizations no longer need to purchase excess capacity to handle periodic spikes in usage. Cloud services scale seamlessly as per demand, so you only pay for what you need at any given time. This optimizes spending and avoids wastage.

Easy Scalability

The cloud provides almost unlimited scalability on-demand. Infrastructure like servers, storage and networking can scale up or down automatically based on usage, without manual intervention. This seamless expandability enables organizations to handle growth easily without having to worry about capacity planning.

There is no need to purchase hardware weeks or months in advance to provide headroom for future growth. With the cloud, you can deploy hundreds of servers with a few clicks in minutes when needed. This level of effortless scalability is impossible to achieve with traditional on-premises IT systems.


The flexibility offered by cloud computing is unparalleled. IT resources can be deployed, accessed or decommissioned on-demand in real-time as business needs evolve. This enables much faster development and testing cycles for apps and services.

With cloud infrastructure, organizations can swiftly set up test environments, conduct testing, then decommission those resources as needed. This facilitates easier experimentation and innovation.

The cloud’s inherent flexibility also allows businesses to adapt their IT infrastructure rapidly in response to changing market conditions or new strategic initiatives. Overall agility and the ability to pivot quickly is enhanced.

Universal Access

With cloud computing, data and applications are centrally stored and managed in the cloud. This makes them accessible from any location, at any time and on any device. Workers can securely access company data, apps or emails whether they are in the office, at home or travelling.

The universal accessibility enabled by the cloud fosters greater mobility and collaboration. Employees in different office locations, or even different countries, can work together seamlessly on projects. Critical data can also be accessed in the event of disruptions like natural disasters that prevent employees from accessing on-premises systems.

Enhanced Resilience

Leading cloud providers have extremely resilient and redundant cloud architectures spanning multiple data centers and geographical regions. Customer data is replicated across multiple data centers to minimize the risk of loss. Intelligent failover systems ensure application uptime by rapidly shifting traffic in the event of an outage.

This high degree of inbuilt redundancy enables rapid recovery from unplanned downtime or outages caused by factors like human error, software bugs, natural disasters or cyber attacks. Overall business continuity capabilities are enhanced when using the cloud versus on-premises infrastructure.

The cloud also enables superior backup and disaster recovery processes. Critical data can be backed up in near real-time and stored in geographically diverse locations for maximum data protection. If disaster strikes, systems can be restored faster than with traditional backup systems.

Key Considerations for Cloud Migration

Migrating business systems and data to the cloud is a major strategic move that requires careful planning and execution. Following proven cloud adoption leading practices helps ensure a smooth and successful transition:

Cloud Migration Strategy

A comprehensive cloud migration strategy document should outline the project’s scope, objectives, timelines, costs, resources, security protocols, testing processes and more. Defining the blueprint upfront and securing executive buy-in is key to keeping the complex initiative on track.

The strategy should also cover workload evaluation, deployment models, training needs, communication plans and steps to optimize cloud spending after migration. Partnering with experienced consultants can help organizations develop and execute a robust cloud migration strategy.

Workload Evaluation

Before migration, conduct a detailed evaluation of your technology infrastructure and workloads. Assess each system’s cloud suitability based on factors like security needs, integration requirements and organizational readiness. This analysis helps identify which applications can move to the cloud quickly and which need re-platforming or re-architecting beforehand.

Prioritizing workloads and creating a phased migration schedule ensures smooth progress towards business objectives. Apps with minimal change requirements can migrate first to deliver quick wins. More complex workloads can transition in later phases.

Cloud Deployment Model

Evaluate whether a SaaS, PaaS or IaaS model best suits your workloads based on needs like control, capability and complexity. SaaS provides turnkey business applications. PaaS offers development tools and hosting. IaaS provides raw computing resources.

Assessing workloads helps determine optimal deployment models. For instance, a custom AI application may warrant an IaaS model for access to GPUs, while an HR system can adopt SaaS. A hybrid model combining multiple approaches may suit some organizations.

Expert Assistance

Consider partnering with experienced cloud migration consultants who can help you navigate challenges like legacy system integration, security, network latency and application refactoring. Their technical expertise and best practices can help avoid pitfalls.

Managed service providers can also manage cloud infrastructure, optimization, security, costs and compliance post-migration so your team can focus on innovation. Leveraging qualified external expertise boosts migration success.

Robust Security

A cloud migration strategy must encompass stringent security measures like access controls, data encryption, identity and access management, network security, and compliance monitoring. Multi-factor authentication adds an extra layer of protection.

Security must be woven throughout the cloud adoption process, not treated as an afterthought. This ensures risk mitigation from the start and helps win buy-in across the organization.


After migrating to the cloud, continuously monitor critical parameters like usage trends, cost optimization, system performance, and security to maximize results. Monitoring provides visibility into cloud resource utilization so you can right-size workloads and reduce waste.

Tools like Azure Monitor offer unified views into infrastructure health and application performance. Monitoring cloud costs is also essential to avoid unexpected spikes in spending.


Provide sufficient training to employees on new cloud platforms, tools, processes and responsibilities. Hands-on workshops ensure personnel can use cloud technologies efficiently and follow best practices, especially for critical roles like developers or security analysts. Training minimizes business disruption.


Conducting extensive testing before full cloud migration is crucial. Set up test environments in the cloud to assess factors like performance, interoperability, security and user experience. Fix any issues before going live.

Testing also familiarizes employees with cloud-based operations. Investing time upfront in rigorous testing reduces glitches and enables smoother adoption across the organization after migration.


For most enterprises today, migrating to the cloud has become an imperative to achieve the agility, innovation and resilience needed to drive success in volatile markets. With careful planning and support from qualified experts, companies can successfully transition their workloads to the cloud and leverage its myriad advantages.
