As far as the current generation of businessmen can remember about their waking lives, businesses have always been about reduction. Go labor-less, paperless, serverless, etc. It is about growth arising from the reduction of managing stress. Computers were once as revolutionary as typewriters in the prior decade, internet and cloud storage were overtaking computers and there are many new things getting into the trend that is about to clean sweep the era of storage and bulky applications. Migrating to these de novo trends isn’t bling; it is the technological realism.

What will you find if you unzip your existing IT infrastructure?
Irrespective of the size of your business or the size of your technological investment, every kit will have at least:
- People to install and manage things
- Physical machines or hardware
- Operating Systems
- Internet platforms
- Storage spaces
- More programs
- More applications
- More data
Each of these components acts as a distinct but interdependent pocket containing further technical items. You may own or rent all of it; you may own or rent a part of it; you may own or rent a micro-part of it. This balancing of owning and renting (also called tenancy) is infrastructural management and also says it’s a cloud infrastructure management.
It is the entire IT system that was advanced in its heydays but now is superseded by new systems. So, all the servers and past generation computers along with their rooms and management personnel are widely known as legacy systems.
Present-day and futuristic scenario
Everything is on the go.
Massive amount of information is leaping into the industry and many businesses are availing opportunities through this information. Instead of producing and selling the hardware, cloud vendors such as AWS, GCP, and Azure are letting Services, viz, IaaS, SaaS, PaaS, etc. With the use of a few credentials, you can use these services anywhere and as much as you need – popularly termed as flexibility and scalability. To avail of this ease of business, you need to do:
blending different setups for smooth functionality and inter-communication.
Shifting some or all of the software, programs and application bulk to a different setup (cloud in the modern sense)
Upkeep of the modern IT environment.
Benefits of yesterday, essentials of tomorrow
Bugs, errors, lack of hygiene, unavailable components, and other tonnes of problems keep poking into the sanity of legacy systems. Stepping ahead to the cloud is an easy and obvious answer. That does not mean you have to scrape away your existing investment. Your Management Service Provider (MSP) will integrate, migrate, and maintain both the cloud and the on-premise structure – known as the hybrid environment.
As said above, even if your existing IT infrastructure is just one computer, it still has a lot of micro-components. From the tenancy of a virtual machine (a monolithic computer in the cloud that you can access through the internet) to borrowing little workable space, the scenario is highly expansive. In contrast to the traditional methods, microservices allow your team to build and run applications in small segments. In case one segment does not perform well, you won’t have to uproot the whole cycle, just fix the portion where the error is arising. Containerisation is a fine example here. Why is it getting popular?
Loosely coupled independently maintained services
Based on the single responsibility principle
Easy to scale, both up and down
Freedom of choice in language and technology
Agile/faster development cycles
More secure than monolith as infected programs won’t self-execute
Time to migrate
Migration isn’t one thing; it is an integration of various services clubbed together as one action plan. Before the actual migration, your MSP will make an assessment chart along with respective solutions and suggested vendors. This distribution of services and solutions is done on the basis of the singular needs of your business, both current and arising. Then migration is done, followed by fixations. Higher the quality of migration services, lesser will be the impact/disturbance in your business operations. Every MSP has her own work plan that distinguishes them from others.
