Infrastructure as a Service (IaaS)
It is another name for lift and shift strategy. It involves lifting existing on-premise infrastructure and moving it into a cloud environment. It is an easy cloud migration solution to resolve on-premise power outages, improve network bandwidth, globe data access, refresh or upgrade hardware. It is a big saving solution for all small businesses, no need to purchase on-premise computer equipment, and have less overhead expenses.
Function as a service (FaaS)
It is serverless platform that customers can develop, manage applications, and databases into the cloud environment. While requiring a programmer to rewrite existing application codes and requiring a higher upfront cost for resource setups; it is still the most cost efficient approach to take advantage of the cloud native frameworks since the cloud computer only inquires for a cost while application code is running.
Re-platform
For clients who are having problems upgrading systems horizontally caused by operation limitation. Re-platforming will allow you to upgrade your platform to the next level and enjoy some of the features only offered by the native cloud frameworks. Some features include: Manage upgrades and revamps more easily. Efficiently add new features. Integrate with future partners and third party solutions. Reduce overhead cost.
Re-architect
It will need to be rewrite the existing monolithic application code to be match the cloud native support environment. It requires multiple programmers to work long hours to completely transform it into the cloud native support environment, but the overall improvement will be worth company's long term investment if it is for horizontally scaling for applications, or data intensive application.
Hybrid cloud integration
This type of service connects the existing datacenter into a cloud environment and gains capabilities of cloud native frameworks while allowing access to most of the data locally or using it as disaster recovery site. It can be set up to improve storage performance or slow migration into the cloud environment.
