9 Important Steps for Cloud Migration
Last Updated: 16 Jul 2021
Businesses continue to invest heavily in the IT infrastructure and additionally the licenses are required for both software and hardware which essentially involves cost and time. As businesses revolve around ways to reduce their costs and ease their operations, it is at this particular point, the concept of cloud migration comes into place. Cloud migration is the process of moving databases, applications, and IT processes of businesses into the cloud.

This cloud migration or cloud computing effectuates the move from on-premise or legacy infrastructure to the cloud. This legacy infrastructure includes servers, networking equipment, apps, databases, and other software or hardware infrastructure which can be moved to the cloud through the process of cloud migration.
There are many benefits businesses get with cloud migrations such as agility, flexibility, cost-effectiveness, improved CX, etc. With many leading cloud service providers, businesses can get services on-demand and can pay only for the resources they use. Thus, more and more businesses are moving towards the cloud. There are interesting facts and some statistics stated by leading research analysts on cloud migration.
● Forrester predicts that the global public cloud infrastructure market will grow 35% to $120 billion in 2021. Alibaba cloud will take the Third revenue spot globally, after Amazon Web Services (AWS) and Microsoft Azure.
● According to Forbes, 32% of IT budgets will be dedicated to the cloud by 2021.
● A recent survey conducted by Flexera on 750 enterprises and small-to-medium businesses (SMBs), in the first quarter of 2020 revealed that the vast majority of respondents (93 percent) have already employed a multi-cloud strategy.
● According to Enterprise Cloud Solutions, half of the U.S State and Federal governments heavily use the cloud. On a similar note, another FedRAMP Survey Results Report states that the governments in the United States, especially in bigger cities, are increasing their cloud adoption especially following the initial COVID-19 outbreak.
● As per the news published by The Hindu, Tech giant Microsoft has witnessed an over 775% increase in demand for cloud services post-pandemic. The COVID-19 outbreak across the world led companies to shift from on-premise IT infrastructures to the cloud
All these above data signifies how important it is for businesses to look upon cloud migrations. It is also predicted that multi-cloud will dominate post-pandemic and COVID-19 has been a major driving force for the accelerated demand of hybrid and multi-cloud models for businesses. Moreover, with the huge number of benefits of the cloud, businesses are moving towards cloud adoptions rapidly.
Cloud computing helps in scaling up the business by supporting large workloads. Unlike on-premise infrastructure, it does not require any physical setup of assets like servers, networking equipment, software licenses, etc.
Cloud delivers greater agility with IT resources and helps businesses to scale during surges or seasonal sales with loads of users accessing the resources.
Cloud computing enables businesses to add or take away resources as and when needed. Businesses can quickly expand or decrease computer processing, memory, storage, etc. to meet the ever-changing needs of their customers and business needs. Also, employees and customers can access cloud services from anywhere and anytime.
In cloud computing, businesses can pay only for the resources used. Also in cloud computing, everything is handled by the cloud provider such as upgrades, maintenance, etc., and thus reduces overall costs to businesses.
Cloud computing helps businesses to increase performance and delivers improved user experience. With the help of apps and websites hosted on the cloud, data is readily available to customers which reduces latency and improves performance.
Cloud computing helps businesses to shift from Capital Expenditure (CAPEX) by shifting from an operating expenses model to a pay-as-you-go model which is beneficial for businesses.
Cloud providers keep in check of all security and compliance policies to ensure that sensitive data is safe on the cloud. Cloud providers take care of all policies and thus businesses need not worry about data leaks or loss while adopting cloud migration. They also ensure automatic security updates to their systems protect them from vulnerabilities.
Unlike traditional IT systems that need employees to spend the entire day on tedious maintenance of costly equipment, the public cloud does not need much human support for maintenance. This frees up employees to focus on more important tasks which ultimately helps in driving greater outcomes for businesses.
Many of the cloud providers ensure and provide monitoring of apps or machines and immediately notify businesses of any outage or downtime. More importantly, cloud service providers subsequently perform disaster recovery with automatic backup and logging of the key metrics to provide information on what caused the issue.
Migrating to the cloud is an important aspect for businesses, and even before migrating to the cloud, businesses across domains and industries should try to understand the below points:
● Take a stance on the cloud infrastructure stack flexibility before opting for cloud migration
● Identify cross-application dependencies before planning the migration waves and plan to migrate all dependent systems together
● Identify logical sequencing of migration waves. For example, if accessing some internal applications which require a VPN system to be set up, your VPN server needs to be migrated before the internal applications
● Have an understanding of the probable workloads that can be moved and which cannot be moved to the cloud
● Analyze or get an understanding of the security and safety of authentication and authorization that will be given by the cloud provider
● Get a clear understanding of the customer access to your services and the extent of availability from the cloud provider during migration along with disaster recovery processes
● Get an understanding of databases as they are usually encrypted, hence consider encryption and decryption aspects while moving to the cloud
● Get an understanding of the security and compliance challenges that might crop up during the migration
● Take up a cost estimate for cloud migration and analyze the ROI to decide upon cloud migration
After analyzing the above points, then businesses can move their data, apps, databases, etc. to the cloud by following an effective cloud migration process.
Cloud-based platforms have helped enterprises to reduce time-to-market and eliminate upfront costs. Due to this cloud-based solutions are in high demand. But some issues related to data security, privacy, integration, and application performance pose a great challenge to successful application migration to the cloud. Businesses require cloud-based testing to ensure successful cloud implementation and to realize the complete benefits from cloud solutions.
TestingXperts (Tx) helps you define an effective strategy to test the cloud so that you can address all the challenges and pitfalls. Software testing in the cloud usually focuses on functional testing of the application, and it also needs a strong emphasis on non-functional and cloud-specific testing. Tx adopts this end-to-end approach to ensure high quality across all aspects of cloud implementation. We have experience in testing leading SaaS products and understand the associated complexities. We bring specific domain expertise in various industry verticals along with proven experience in other non-functional cloud testing services.
