 An SLA (service level agreement) is a contract between a cloud service provider and a cloud customer that defines the expected level of service, performance, availability, and reliability of the cloud service. An SLA also specifies the contractually allowed downtime for a cloud-hosted application, which is the maximum amount of time that the application can be unavailable or inaccessible without violating the SLA. The contractually allowed downtime is usually expressed as a percentage of uptime, such as 99.9% or 99.99%, which corresponds to a certain number of hours or minutes per year, month, week, or day. For example, an SLA with 99.9% uptime means that the cloud service can be down for up to 8.76 hours per year, or 43.8 minutes per month, or 10.1 minutes per week, or 1.44 minutes per day. If the cloud service provider fails to meet the SLA, the cloud customer may be entitled to compensation or other remedies, such as credits, refunds, or termination of the contract. References: CompTIA Cloud Essentials+ CLO-002 Certification Study Guide, page 27-28; CompTIA Cloud Essentials+ Certification Training, CertMaster Learn for Cloud Essentials+, Module 2: Business Principles of Cloud Environments, Lesson 2.4: Cloud Service Agreements, Topic 2.4.2: Service Level Agreements

The best solution for this scenario is Virtual Desktop Infrastructure (VDI). VDI is a cloud service model that provides users with virtual desktops that run on a centralized server. Users can access their virtual desktops remotely from any device, such as a laptop, tablet, or smartphone, using a thin client or a web browser. VDI enables users to access business applications without installing them on their own devices, which ensures that these applications are only installed on company-controlled equipment. VDI also allows users to modify their personal working environments, such as desktop settings, wallpapers, or preferences, which are saved on the server and persist across sessions. VDI can offer benefits such as improved security, reduced hardware costs, centralized management, and enhanced user experience. The other options are not the best solutions for this scenario. Single Sign-On (SSO) is a cloud service that enables users to log in to multiple applications or systems with one set of credentials, which simplifies authentication and improves security. However, SSO does not provide users with remote access to business applications or personal working environments. Secure Shell (SSH) is a network protocol that allows secure remote access to a server or a device using encryption and authentication. SSH can be used to execute commands, transfer files, or tunnel network traffic. However, SSH does not provide users with virtual desktops or business applications. Virtual Private Network (VPN) is a network technology that creates a secure connection between a remote device and a private network over a public network, such as the Internet. VPN can be used to access network resources, such as files, printers, or applications, that are not available otherwise. However, VPN does not provide users with virtual desktops or personal working environments. References: CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002), Chapter 2: Cloud Concepts, Section 2.3: Cloud Service Models, p. 64-65

A lift and shift migration approach is the best option for a company that needs to move rapidly to a cloud environment. A lift and shift migration, also known as rehosting, involves moving an existing application and its associated data to a cloud platform without changing the app’s architecture1. This approach is suitable for applications that are compatible with the cloud provider’s infrastructure and do not require significant modifications or optimizations to run in the cloud2. A lift and shift migration can offer the following benefits for a company that needs to move quickly to the cloud34:

• Speed and simplicity: A lift and shift migration can be done faster and easier than other migration approaches that involve refactoring, replatforming, rebuilding, or replacing the application. A lift and shift migration can leverage automated tools and processes to reduce the manual effort and complexity involved in the migration. A lift and shift migration can also minimize the risk of errors, bugs, or compatibility issues that may arise from changing the application code or configuration.
• Cost savings: A lift and shift migration can help a company save costs by avoiding the expenses of maintaining or renewing the data center contract, hardware, software, or licenses. A lift and shift migration can also help a company take advantage of the pay-as-you-go pricing model and the scalability and elasticity features of the cloud, which can reduce the operational and capital expenditures. A lift and shift migration can also enable a company to benefit from the security, reliability, and performance enhancements offered by the cloud provider.
• Future flexibility: A lift and shift migration can help a company move to the cloud without disrupting the existing business operations or workflows. A lift and shift migration can also provide a foundation for future cloud optimization or modernization initiatives, such as refactoring, replatforming, rebuilding, or replacing the application to leverage the native cloud services and features. A lift and shift migration can also allow a company to adopt a hybrid or multicloud strategy, which can increase the availability, resilience, and agility of the application.

 A network report is a document that provides information about the network usage and performance of a cloud service. It can help the company identify the network-related factors that may affect the responsiveness of the application, such as bandwidth, latency, jitter, packet loss, and throughput. A network report can also help the company monitor the network costs and optimize the network configuration to reduce the monthly bills.

A memory report, a compute report, and a storage report are documents that provide information about the memory, compute, and storage resources of a cloud service, respectively. They can help the company understand the resource consumption and performance of the application, but they are not the first documents to examine for the responsiveness issue. References: CompTIA Cloud Essentials+ CLO-002 Certification Study Guide, Chapter 4: Operating in the Cloud, Section 4.3: Monitoring Cloud Services, Page 133
