IaaS stands for Infrastructure as a Service, and it is a cloud service model that provides customers with access to virtualized computing resources, such as servers, storage, and networks. In the IaaS model, the customer is responsible for patching the operating system (OS) of the virtual machines, as well as installing and managing the applications and data. The cloud service provider (CSP) is responsible for maintaining the physical infrastructure, such as the hardware, power, cooling, and security. Therefore, IaaS passes the responsibility of patching the OS to the customer, unlike PaaS, DBaaS, or SaaS, where the CSP handles the OS patching and updates.

Detailed Explanation:

B. Autoscaling with load balancing: Autoscaling adjusts resources based on demand, ensuring that unused compute capacity is released, reducing costs. Load balancing distributes traffic, preventing resource overuse.

The best option to perform the database migration is to create a replica database, synchronize the data, and switch to the new instance. This option can help meet the restricted SLA and avoid offline time for the database. Creating a replica database can help copy the data from the source to the destination without interrupting the database operations. Synchronizing the data can help ensure that the replica database is updated with any changes that occur in the source database during the migration process. Switching to the new instance can help complete the migration and activate the new database in the cloud. This option can also help avoid the network bandwidth limitation and the large size of the data.
