Evolution of the Cloud- an Overview
Today, cloud computing is one of the key influences to attain business transformation. However, it is a disruptive technology, and the future of the cloud started shaping up during the 1950s when computational services were the forte of distributed systems and mainframe computing. During that era, the systems were giant and expensive machines that functioned over a time-sharing network within a restricted location. As a result, it encountered massive traffic and sluggish processing time. For quick and efficient operations, computing systems expanded the functions during the 1980s with cluster computing. In cluster computing, the computer nodes were connected via a high bandwidth network. However, the location restrictions persisted. Later in the 1990s, the internet and virtualization were introduced, which opened the avenue to interconnect the systems located at different geographic locations and allowed users to run multiple processes over the same hardware. It was during this time that accessing the applications from the remote location found their roots.
During the early 2000s, the concept of Web 2.0 emerged, where the development of interactive websites was the prime focus. During this time, organizations like Google, Facebook, Twitter, etc., started introducing their web pages. Needless to say, that, the concept of social media also arose during this time. Later on, rapid technological development introduced the concept of utility computing that allows the applications, storage, and infrastructure to be available at metered service on a subscription basis.
These are the phases of the evolution of cloud computing to become what it is today.
Cloud and Digital Transformation
Enterprises agree that innovating the business models with the latest market demand is the key to success. Cloud computing is one of the crucial trends that drive the customer experience and help to gain customer loyalty. The direct impact of cloud computing in future business is that it fuels growth and leads towards business transformation by realigning your business processes. We know how the cloud is advantageous for the business, but considering the limitations and knowing how to overcome it will ease your digital transformation.
“Cloud computing changed the technological aspect and the market dynamics in the business world.”
Ariel Munafo, Founder and Board Member of MarkeTech Group (Interview with Media7)
What Are the Advantages of Implementing Cloud for Business Transformation?
Here is the list to remind you about the advantages of implementing cloud technology for your business:
Cost-efficiency: Shifting to the cloud helps reduce the cost of managing and maintaining data centers and infrastructure. Further, you can also opt for cloud services such as SaaS, PaaS, and IaaS that allow you to pay for the services that you use.
Scalability: The cloud provides almost unlimited storage capacity. Further, it also allows expansion of your operational requirement based on the business needs. You can quickly scale up or down your cloud resources at a reasonable cost. Otherwise, with legacy systems, expansion was expensive.
Easy Deployment and Security: Cloud Deployment is quick and easy compared to establishing an on-premise data center. Further, cloud providers emphasize security by leveraging protection and access control mechanisms to ensure customer data safety.
Improved Responsiveness: Cloud technology is fast and known for its quick action. It has minimal latency for dependent processes. As a result, your business provides prompt results and stays relevant in the market.
Enhanced Backup and Data Recovery: The data in the cloud is flexible, and hence it is easier to back up and restore whenever necessary. Otherwise, running back up of on-premise and legacy data centers was a time-consuming and cumbersome process.
Flexibility and Easy Accessibility: The cloud allows you to utilize its resources as per the demand variations. When the demand spikes, you can add up the features and resources, and when it drops, you can reduce the same. Further, it allows you to access data from anywhere, anytime, through the internet.
Collaboration and Resource Sharing: Earlier with legacy systems, cross-functional collaboration was not easy, and sharing the resources was tedious. Eventually, it affected the overall functioning of the business. With the cloud, your inter-departmental connection is accessible through the internet, making the resource sharing capability seamless to boost the role of cloud computing in digital transformation.
Reliability with Auto Updates: Cloud helps run easy backup and data recovery functionalities to avoid data loss for your business, which was a lengthy task for traditional data centers. Further, regular automatic updates with the latest technology retain the performance quality of your operations. These updates could be up-to-date versions of applications, servers, and processors.
What Are the Main Roadblocks for Cloud Implementation?
Although the cloud brings several benefits, certain aspects are the area of concern for business leaders. According to Statista’s survey in the last quarter of 2020 conducted with the technical managers and business executives, around 81% responded that security is one of the significant challenges of the cloud. Here we list some of the substantial areas where cloud needs to improve.
Data Security: As stated above, data security has always been on the top list of challenges for cloud-based services. Your company data is stored in a shared environment for your cloud service provider’s access to the public cloud. This accessibility for any third-party vendor might increase the risk of data leakage. Further, although the private cloud has an access control mechanism yet, it is vulnerable to cyber-attacks.
Working with Multiple Cloud Environments: As cloud technology flourishes, most organizations use multiple cloud platforms to optimize workloads and control costs for specific business operations. Such cases bring potential security threats while sharing or transferring resources between the cloud environments due to the involvement of multiple cloud vendors.
Data Governance and Regulation Compliance Challenges: You should check whether your cloud service provider has data governance and regulatory compliance to ensure that your critical and non-critical organizational data is safe.
Dependency on the Service Providers: If you are using service from a vendor, you cannot simply transfer to any peer cloud service provider due to incompatibility of technology or other services. Such situations are called vendor lock-in, which makes you dependent on the service providers.
Optimizing Implementation Overheads: Cost management has been one of the most challenging tasks for cloud users. Enterprises often tend to spend a lot of money on the cloud because they lack knowledge about estimating the investment, planning resource utilization, and monitoring the cost of services. As a result, it increases the overheads in several instances.
How to Overcome the Cloud Implementation Challenges to Augment Business Transformation?
Though specific challenges act as a roadblock for cloud adoption, digital transformation and the cloud are interlinked. Therefore, you can formulate some guiding principles for purchasing and adopting the cloud. Here are some of the ways you can plan to tackle the challenges of cloud implementation:
Emphasize on Security: Plan out specific security provisions, such as encryptions, multifactor authentications, keys rotation, and tokenization to safeguard data in the cloud. Further, you can also deploy firewalls preventing malpractices such as SQL injection attacks, etc.
Evaluate Your Cloud Vendor: Establish essential guidelines around compliance and regulatory needs for cloud services. Based on the guideline, you can evaluate your vendor. For example, their policies and work around user identity and access management, data security, response time, etc., can help evaluate your cloud vendors.
Classify the Resources: It is crucial to identify the cloud-ready workloads. You can Shift those workloads first and invest in app modernization to make the other workloads compatible with the move. This classification will help you to control the pricing changes.
Emphasize on Cloud Governance: Establish compliance protocols and governance methods in the security framework that explain the factors such as the number of users, services, and the approvals required for the cloud services.

“Cloud computing is the third wave of the digital revolution.”
Lowell McAdam, CEO of Verizon
There are two ways you can adopt cloud for your business- cloud migration and modernization of applications.
Cloud Migration: A Significant Method to Fortify Digital Transformation
According to Flexera, 94% of the enterprises are using cloud services by now. Cloud and digital transformation are correlated to each other. Migrating to the cloud from legacy infrastructure helps reform your business and opens the avenue towards seamless digital transformation. It brings in innovation and agility to attract market attention.
Cloud Migration is the process that shifts the workloads, data, and other applications from an on-premise server to the cloud server. It is also termed the "lift and shift" process, which moves explicit workloads and applications to the cloud server. This move leverages the cloud features such as automatic scaling, enhanced efficiency, prompt responsiveness, agile performance, robust security, storage, quick computation, and networking.
Vital Tactics for an Effective Cloud Migration
According to research conducted by Multisoft, primarily within start-ups and SMBs, the advantages of cloud computing are instantaneous. Moreover, 80% of the surveyed companies report process enhancements within the first few months of adopting the cloud.
An effective migration strategy is the best way to enable business growth. It also empowers to stay aligned with the digitalization objectives. As a result, businesses are driven towards implementing their migration plan from on-premise to the cloud. The migration strategy is influenced by business vision, goals, and interests. According to Markets and Markets, the cloud migration services market is expected to grow at a Compound Annual Growth Rate (CAGR) of 24.5% by 2022. To carry out a successful cloud migration efficiently and effectively, here are some crucial steps you can consider for an effective shift to the cloud.
Knowing Your Goal
It is critical to have a clear idea about your business goal before making your migration plan. Identifying the goal of shifting to the cloud is about the technology and the upliftment of the organization. Earlier, business and the supporting IT services used to work separately. But now, IT services and businesses work collaboratively because every business needs technical fortification. Otherwise, it would not be able to survive the competition. Adopting cloud platforms is one of the effective ways to leverage the technology for your organization. In addition, it allows you to scale your efficiency by using tailored services automatically.
Strategizing the Shift
Before reaping the benefits of cloud migration, it is crucial to plan out the shift. First, you should identify what you need to move. Determining the cloud-readiness of your current infrastructure and application is crucial. Next, consider the foundation metrics of your infrastructure to align workloads to your assets and applications. It will help you establish key performance indicators (KPIs) for migration, such as time for loading a page, response times, availability of the resources, CPU utilization, memory usage, and conversion rates. Strategizing your migration process has to be well-planned in a way that prioritizes your business objectives and considers the cost analysis pre and post shift.
Selecting the Right Migration Strategy
According to Unisys, one in three cloud migrations remains unsuccessful globally because the cloud is not a part of the core business strategy and is not planned correctly. Therefore, selecting the right migration strategy is one of the integral steps to attain business transformation. The 6Rs of migration strategy are- Rehosting, Replatforming, Repurchasing, Refactoring, Retiring, and Retaining. One of the critical reasons for a successful migration is to identify whether the applications that are supposed to be migrated are ready to perform and produce desired business value in the new environment. If not, then the migration can’t be considered a success.
Choosing the Ideal Platform
Digital transformation and cloud go hand-in-hand. It simply means cloud computing has become the basic foundation of the technologies that enable digital transformation. As a result, based on your business requirement, you need to identify, select, and set the right cloud platform for your business. You need to decide if public, private, hybrid, or multi-cloud environments are the right course of action for your needs. Further, deciding amongst eminent cloud vendors for your organization, such as Microsoft Azure, AWS, and Google Cloud Platform, is an integral step for a successful migration.
Making your Cloud Infrastructure Ready for the Shift
Once you decide on a specific platform for the migration, you need to make it ready to host the on-prem applications. Also, decide and select the suitable applications and cloud services for the new cloud platform. The major cloud services providers offer a wide range of choices that is close to the on-premises offerings. Further, some third-party service providers offer an amalgamation of on-premises and multi-cloud platforms, such as Databricks and Snowflake on AWS and Azure. The cloud platform and services you opt for will also decide the amount of code revision required to make the applications cloud-ready.
Emphasizing on Cloud Governance
Governance defines process, policy, and criteria for effective decision-making. It also helps to measure success, track milestone planning, and scope management. For successful mass application transformation to the cloud, defining a governance model will help to cover security, financial, performance, collaboration, and communication.
Defining Cloud KPI’s
While you strategize the migration plan of your business to the cloud, defining Key Performance Indicators (KPIs) helps you measure how the applications are performing against your expectations. It is crucial to understand that whether your pre-defined KPIs are accurate in the cloud environment. The best KPIs for a cloud migration reflect your migration status and identify any problems within your application. Further, it is ideal if your KPIs help you determine whether the migration is complete and successful.
Maintaining Security During Data Transfer
Understanding your organization's current security requirements, analyzing gaps, and establishing cloud security best practices leverages security controls offered by cloud providers and improves the security scenario based on application requirements. Aligning security with Cloud Controls Matrix (CCM) framework provides essential security principles to control the overall security risks on a cloud platform and service model. It strengthens information security control, identifies consistent security threats and vulnerabilities in the cloud, and provides means to reduce it with standardized security and operational risk management.
Implementing the Movement
Once you follow all the steps meticulously, you’re ready for the shift. However, your migration tactics would depend on the complexity of your applications and infrastructure. Your strategy must also include the risk assessment that can arise due to operational disruption. However, the primary focus should be implementing the migration quickly with reduced cost and utilizing the benefits of cloud migration. To achieve it, you can shift your entire application and analyze how it functions. Otherwise, you can take a more granular approach by moving gradually until the entire application moves to the cloud.

CLOUD INFRASTRUCTURE MANAGEMENT
Article | October 13, 2021
With the growth of modern technologies, businesses are harnessing the power of cloud computing. Cloud computing is a strategic approach that allows on-demand data computing services over the internet on a pay-as-per-use basis. The storing and accessing of data in the cloud is done from a remote data center. As a result, it regulates the investment in costly hardware for an on-premise setup.
“Cloud computing is an innovative way to run your business.”
- Marc Benioff, Founder, CEO and Chairman, Salesforce.
According to the analysis report by the market intelligence firm ResearchandReport, the global cloud computing market size is projected to reach USD 1,251.09 billion by 2028, recording a CAGR of 19.1%. Amongst the different cloud computing models, the three most vital variants are SaaS, PaaS, and IaaS. This article describes the SaaS vs. PaaS vs. IaaS strategies, their comparison to help you determine the best fit for your business.
The Three Most Vital Cloud Strategies for 2022
But before we begin, let us quickly look upon the interesting statistics on SaaS, PaaS, and IaaS in cloud computing by Statista. It states that the global market size for SaaS is expected to reach 172 billion USD, whereas PaaS and IaaS will reach 101 billion USD and 122 billion USD, respectively, in 2022. Several small-scale, medium-sized, or large-scale enterprises are adopting cloud service models to meet digital transformation. As you plan your workload migration to the cloud, it is vital to understand the ideal strategic model for your business by knowing the details and the difference between SaaS, PaaS, and IaaS.
SaaS (Software as a Service)
SaaS offers on-demand, ready-to-use cloud-based applications to the end-users. It is hosted by a provider and is delivered via the internet on a pay-as-you-go subscription. SaaS applications integrate data from diverse storage locations of an enterprise. SaaS providers keep enhancing their products and ensure that their customers use its latest version every time. Some examples of SaaS platforms are Google Workspace, Dropbox, Salesforce, Cisco WebEx, etc.
Benefits of SaaS
Let us consider a real scenario to explain the advantages of adopting a SaaS computing strategy.
How the University of Sydney Leveraged SaaS (Dropbox) to integrate the processes?
The University of Sydney was facing challenges due to disintegration among its multi-data storage platforms. They needed a unified application that is scalable, user-friendly, and easily accessible across their ecosystem for accelerating their research process.The University of Sydney could securely store and connect data to accelerate the research process by leveraging Dropbox. After implementing Dropbox, the university could significantly establish collaboration between their staff and students and external alliances across the globe. Further, they could control the overhead training and infrastructure cost. Governance also became easy with Dropbox, allowing IT teams to utilize their productive time in other crucial tasks. The scalability and user-friendliness were the primary factors that motivated the university to adopt Dropbox.Referring to the above instance, we can infer that a SaaS model can regulate cost, save time, be user-friendly, and scale as per demand. Further, this model is easy to deploy and maintain that needs minimum focus by the company's technical department.
Drawbacks of SaaS
Every pro comes with a con, and SaaS models are no exceptions.
Performance Reliability: SaaS applications are dependent on the internet, and as a result, they might become inconsistent at times. The only way to avoid this is by investing in a stable and high-speed internet connection. Additionally, you can also use software performance management tools to check the performance of SaaS applications at regular intervals.
Data Security: Data Security is one of the crucial aspects of any organization. SaaS apps lack transparency and the ability to protect business-critical data. As a result, some enterprises dealing with confidential information are in two minds to switch to the software-as-a-service model.
PaaS (Platform as a Service)
PaaS model provides a ready-to-use cloud environment for creating, testing, and maintaining software applications. With the PaaS model, you don’t have to build and maintain the infrastructure required for your application. Examples of PaaS models are Windows Azure, LoadSpring, Google App Engine, Apache Stratos, OpenShift, etc.
Benefits of PaaS
“LoadSpring Cloud Platform is more agile and flexible than other available solutions. We provide cloud solutions to our vendors and partners who want their applications to be SaaS-enabled. Our speed, performance, and seamless integration make it the ideal platform to deploy their apps.”
- Stacey Witt, Chief Marketing Officer at LoadSpring (During an interview with Media 7)
With Stacy’s statement, we can sense how a PaaS model can be helpful for your organization. PaaS is ideal for many medium or large-scale businesses because it provides a ready-to-go solution. All you need is an IT support team to handle the data usage and software. However, with the PaaS model, you have control over the performance of your platform.
Let us explain with an instance.
How Atos Used PaaS (LoadSpring) to Solve the Challenges Faced by Siemens?
At the Gas and Power division of globally recognized brand Siemens, the leaders started experiencing a sloth in their locally hosted P6 and wanted to improve the performance.As an IT support provider for Siemens, Atos assisted them in overcoming the scenario. It referred LoadSpring to assess their P6 cloud-hosting. After sequences of operations, the LoadSpring platform enabled P6 to run 10 times faster than the locally hosted version. This enhanced performance saved an hour per user per week. As a result, Siemens considered their workload migration to LoadSpring that helped them increase their project efficiency.
Drawbacks of PaaS
Here are some of the loopholes to consider while adopting PaaS.
Dependent on Third-Party Vendor: PaaS solutions are vendor-dependent. If you wish to change your existing PaaS model, you may face compatibility issues. It is primarily because all the vendors might not support the same framework to develop and run the applications.
Security Concerns: A potential risk for your application’s back-end data and hosting code may arise because it is stored at the vendors’ site. You should cross-check and verify the security and compliance protocols with your vendor beforehand.
IaaS (Infrastructure as a Service)
IaaS is one of the cloud computing models that provides virtual data centers to medium or large-scale enterprises. It includes the entire infrastructure to research and develop advanced technologies on the cloud. IaaS is a self-service model that hosts website and software solutions and performs data mining and analysis. Examples of popular IaaS models are Amazon Web Services (AWS), Microsoft Azure, Google Compute Engine (GCE), Cisco Metacloud, etc.
Benefits of IaaS
To understand the advantages of IaaS, let us consider a situation faced by the globally acclaimed OTT platform- Netflix.
How Netflix Depended on IaaS (AWS) For a Scalable and Reliable Infrastructure?
Netflix experienced a momentary surge in viewers and subscribers due to the extreme changes across the world. To accommodate this demand, it needed an infrastructure that could scale simultaneously. As a result, Netflix trusted AWS to help it modernize improved computation, storage, and infrastructure that allow the company to scale rapidly, function steadily, and match up to the capacity needs across the world.
Taking cues from the above example, we can deduce the benefits of using IaaS. IaaS cloud service model is highly scalable, easy to automate and deploy, flexible, and reliable. It also comes under the pay-as-you-go model and hence proves to be cost-efficient as well.
Drawbacks of IaaS
Here are some of the limitations of IaaS that you need to consider.
Train Your People: IaaS model will provide the complete infrastructure for your business, and you need to ensure the smooth running of all the operations. Hence, it becomes inevitable for your team to have thorough knowledge about the deployed model. Otherwise, you might have to face unnecessary hindrances.
Managing Downtime: Enterprises might encounter downtime with IaaS, restricting their access to operational data and applications. As a result, it might affect their process- efficiency for some time.
