Explanation:
This type of question are asked to create confusion.
Following are the five phases of SDLC:
1. Planning and requirements analysis: Business and security requirements and standards are being determined. This phase is the main focus of the project managers and stakeholders. Meetings with managers, stakeholders, and users are held to determine requirements. The software development lifecycle calls for all business requirements(functional and nonfunctional)to be defined even before initial design begins. Planning for the quality-assurance requirements and identification of the risks associated with the project are also conducted in the planning stage. The requirements are then analyzed for their validity and the possibility of incorporating them into the system to be developed.
2. Defining: The defining phase is meant to clearly define and document the product requirements to place them in front of the customers and get them approved. This is done through a requirement specification document, which consists of all the product requirements to be designed and developed during the project lifecycle.
3. Designing: System design helps in specifying hardware and system requirements and helps in defining overall system architecture. The system design specifications serve as input for the next phase of the model. Threat modeling and secure design elements should be undertaken and discussed here.
4. Developing: Upon receiving the system design documents, work is divided into modules or units and actual coding starts. This is typically the longest phase of the software development lifecycle. Activities include code review, unit testing, and static analysis.
5. Testing: After the code is developed, it is tested against the requirements to make sure that the product is actually solving the needs gathered during the requirements phase. During this phase, unit testing, integration testing, system testing, and acceptance testing are conducted.

Definitions:
Business continuity: The capability of the organisation to continue delivery of products or services at acceptable predefined levels following a loss of service.
Business continuity management: A holistic management process that identifies potential threats to an organisation and the impacts to business operations those threats, if realised, might cause. It provides a framework for building organisational resilience with the capability of an effective response that safeguards the interests of its key stakeholders, reputation, brand, and value-creating activities

A workload is a unit of processing, which can be in a virtual machine, a container, or other abstraction.
Workloads always run somewhere on a processor and consume memory. Workloads include a very diverse range of processing tasks, which range from traditional applications running in a virtual machine on a standard operating system, to GPU- or FPGA-based specialized tasks Reference: CSA Security Guidelines V.4(reproduced here for the educational purpose)

ISO 270017 provides guidance on the information security aspects of cloud computing. recommending and assisting with the implementation of cloud-specific information security controls supplementing the guidance in ISO/IEC 27002 and other ISO 27k standards.
