In a cloud environment, high availability is typically ensured through the use of a load balancer. A load balancer distributes network or application traffic across multiple servers, ensuring that no single server becomes overwhelmed and that services remain available even if one or more servers fail. This setup enhances the reliability and availability of applications.
Load balancer: Ensures high availability by distributing traffic across multiple servers or instances, preventing overload and ensuring continuous availability.
Access broker: Typically refers to a service that facilitates secure access to resources, not directly related to high availability.
Cloud HSM (Hardware Security Module): Provides secure key management in the cloud but does not specifically ensure high availability.
WAF (Web Application Firewall): Protects web applications by filtering and monitoring HTTP traffic but is not primarily focused on ensuring high availability.

PAM software helps manage and secure privileged accounts and access credentials. It allows admins to grant temporary, controlled access to critical systems without sharing passwords directly. PAM software can track, monitor and log all activities performed by the consultant.

Virtual Desktop Infrastructure (VDI) allows a company to host desktop environments on a centralized server. Offshore teams can access these virtual desktops remotely, ensuring that sensitive data stays within the company's infrastructure without the need to provide physical devices to the team. This solution is ideal for maintaining data security while enabling remote work, as all data processing occurs on the company's secure servers.
