By 2020, a massive leap of 83% of enterprise workloads will be tackled by cloud-based services, says in a survey report by LogicMonitor. Further, the growing grip of Artificial Intelligence, Machine learning, and 5G network technologies contribute to its advance in the public and private marketplace.
Here, let’s check the benefits and strategies of cloud migration in 2020
What is Cloud Computing?
The process of transferring digital business processes into the cloud is called cloud migration. Cloud migration is similar to a physical transfer, except that instead of packing up and moving items on a physical level, it requires transferring data, applications, software products, and IT processes from certain data centers to larger and more flexible data centers.
Types of Cloud Migration
Based on the service requirement enterprises can choose the right cloud option for their business. Companies can use cloud service in multifarious forms. They can host their IT infrastructure, make it their business platform, deploy business software, etc.
Software as a Service (SaaS)
One of the most adopted cloud migration is SaaS. It enables the users to access the application from anywhere via the web. To illustrate, if a content sharing application moved to the cloud, it becomes more flexible and highly available. Users don’t need to install the software anymore. It is an excellent way to save a lot of money for the enterprise. Also, it improves the operational agility and functional features of applications dramatically.
Platform as a Service (PaaS):
It is the process of shifting the on-premise platform to the cloud. It is an easy method that can be done without technical expertise. It accommodates external hardware and software and allows building applications upon the platform. Further, the users can tailor the application to their specific business model. It offers all sorts of cloud-native benefits to the users.
Infrastructure as a Service (IaaS):
It is the process of transferring computing infrastructure such as servers, operating systems, networks, storage in the cloud. Users can access all these computing resources through virtual gateways. It provides unlimited scalability and mobility to the users. Google compute engine, Amazon web series (AWS), Microsoft Azure are some of the best examples of IaaS.
Cloud Migration Benefits
Cloud platform holds a lot of surprising benefits for all of its entrants. However, all it takes an appropriate migration strategy and a fitting cloud hosting platform. Businesses that provide Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) can gain unprecedented growth prospects from cloud platforms. Moreover, it enabled all sorts of enterprises to upscale their competency in the market where once the tech-giants alone reigned.
Let’s see the surprising benefits of cloud migration
One of the nerving challenges that every enterprise face across their business journey is scalability. On-premise infrastructures are not so interested to possess a dynamic nature as the business needs. It involves complex infrastructure modifications and an exorbitant budget. As a result, small and medium scale businesses were struggled to provide competent service and pulled back in the market.
The advent of cloud service changed the entire game and empowered businesses of all kinds to improvise at scale. As the business demands, they could scale up and down. Including IT resources, enterprise management, business efficiency, and resource distribution, cloud technology overturned the entire business strategy overnight.
Once there was a time that a slight network crash/ a server snag spoils the entire day of business. Amazingly, on could, users can request the essential service and launch via any connected devices. Cloud services are highly available at any scale. The incredible mobility offered by cloud technology and its allied services is making it possible. Users can access data and authorized applications all from their comfort with an internet access point.
This improves productivity and eliminates the haunting menace ‘downtime’ significantly from enterprises. Also, employees could work from their homes and on devices of their choice as well. It redefined the work nature and production paradigms.
Cloud-based services are way affordable than the old-school model of business IT infrastructure. It made available IT services and resources at a cheap cost. The cost splashed for dedicated servers, on-premise hardware and software infrastructure, talent resources, maintenance was dropped down noticeably. With the help of resource APIs and intelligent programs, the same task that costs millions reduced into the task of implementing cost. Besides,
Further, services like AWS cloud hosting offered Pay-as-you-go payment methods to enable everyone to afford cloud computing technologies. On the spree to acquire the target market, today, many businesses are delivering the best service to the users via cloud technologies.
Cloud platforms offer good security features for a reliable business operation. Similar to the tight security measures using in on-site data centers and storage servers, all transactions across the cloud environment are wrapped with strict security measures.
Also, in a cloud platform, as the business infrastructure grows, security measures will adjust with the demand. The software-based intelligent security tools manage to maintain a secure atmosphere all across the environment. Also, it prevents unauthorized access to databases with stringent security strategies.
Cloud computing services are highly measurable in nature. Without any shortage or shed-load, it provides measured services as per the requirement of users. Users can pre-plan their business requirements and request adequate service on demand.
Thus, the cloud enables the service provides and the users to measure the service that is delivered and accessed. As a result, the measurability of cloud services eliminates the huge budget requirement for IT services for businesses.
Cloud services are very flexible and equally scalable. Businesses with unpredictable customer trends gain more benefits from this feature. Also, with the cloud service enterprises can deploy and maintain application with operational agility across any platform or devices. The automated tool with intelligent features provides flexible solutions for business needs.
Cloud Migration Strategies
Cloud migration involves a lot of delicate tasks that require greater attention. The mode of movement is different for different business models. Hence, while deciding to migrate, enterprises are required to choose the right strategy for a smooth as well as an uninterrupted business continuation.
Rehosting (Lift and Shift):
The lift and shift method is an efficient migration strategy for enterprises that are continuing with their legacy software. Rehosting the same application on the cloud environment enables them to bypass extra learning time and expense. It probably causes no/least disruption across the business function for enterprises.
In the rehosting method, unlike a full-fledged cloud-based application, the performance ratio seems little diminished. Since it is just moving the application to a new location, it cannot produce all the gleaming benefits of the cloud environment. Yet, it reduces the upfront cost and easy migration.
It is the process of swapping the application at the source level and making it a cloud-native application. Businesses which requires end-to-end cloud support suggests to re-platform their business architecture. Replatforming helps the enterprises to scale, measure, flexible, resilient, and highly available all across the web. However, it involves higher upfront costs and complicates to execute. Replatformed applications are modular in design and quite easy to maintain.
This model is also called as re-factoring. Re-architecting facilitates to replicate the legacy applications to the cloud platform. It enhances the existing legacy application performance and adds adequate features such as agility, scalability, and mobility from the cloud platform. It provides cloud-native services that help to save a lot of money.
To re-architect it is imperative to select the most appropriate cloud platform. A suitable platform helps to attain an agile working environment with relevant services.
A very example to explain repurchasing migration strategy is Email service. As a SaaS, email service simplifies the entire communication task with a single take. Repurchasing offers plenty of competency advantages for companies. It is a fast solution model to solve business problems. It enables employees to focus more on productive outputs than technical hassles.
Importance of Cloud Computing
Cloud migration is a complex process of shifting applications, data, and the on-premise business architecture to an on-demand computer system resource called- Cloud. Cloud migration enables enterprises to deliver service anywhere through the internet. It eliminates the immediate requirement of direct management of systems and networks by the users.
To meet the increasing customer demands and perform a competitive business strategy, replanting the enterprise infrastructure into a business-appropriate cloud platform is imperative. Cloud platforms assemble a fertile ground for every business application to grow unlimited. Hence, the importance of adapting to a suitable cloud environment is high as the competition in the market rises.
There are verities of migration practice for the business enterprises, but all of them possess distinct features and migration methods. Of the different cloud migration models, the most adopted one among the business world is the ‘lift and shift’ approach. The prominent other is the cloud-to-cloud migration model. Yet again, there is another migration method that transfers data and applications from the cloud environment to the on-premise datacenters called de-clouding/uncloud. However, the model and the mode will be determined by the security requirements, migration budget and functional parameters of the enterprise.
Cloud migration is a critical process that involves numerous factors. Understanding the relevant demands to upscale business and leverage the business prospects, enterprises can choose the best suite. It confines delicate business decisions to complicated technical checklists. Only the proper combination of all these strategies as well as operational elements could deliver a wholesome cloud migration experience.
