f5 Experience

 As a network engineer with experience on F5 LTM, GTM, and ASM, some of my daily job activities would include configuring, maintaining, and troubleshooting these devices to ensure optimal performance and availability of network resources. I would also be responsible for monitoring network traffic and identifying and resolving any issues that arise. Additionally, I may be responsible for implementing security measures such as firewall policies, intrusion detection and prevention, and SSL offloading using the F5 ASM. Some other roles and responsibilities could include:

• Deploying and maintaining load balancers, traffic managers, and application security devices
• Configuring virtual servers, pools, and nodes
• Managing DNS, Global traffic management (GTM), and Local traffic management (LTM) configurations
• Creating and managing iRules, policies and profiles
• Implementing and maintaining high availability and disaster recovery solutions
• Collaborating with other teams to ensure proper integration of F5 devices with other network infrastructure
• Keeping up to date with the latest F5 software releases and security patches.

LTM

F5 LTM (Local Traffic Manager) is responsible for load balancing traffic at the local level, within a single data center. Some responsibilities for an LTM administrator may include:

• Configuring virtual servers, pools, and nodes: Virtual servers are used to define the IP addresses and ports that will be used for load balancing. Pools are used to define the group of servers that will handle the incoming traffic. And nodes are the individual servers that make up a pool.
• Managing LTM configurations: This includes setting up load balancing methods, such as round-robin, least connections, and IP Hash, as well as configuring persistence methods, such as cookie and source IP.
• Managing high availability and disaster recovery solutions: This includes setting up device groups, failover, and sync-failover configurations to ensure that traffic continues to be served even in the event of a device failure.

GTM

F5 GTM (Global Traffic Manager) is responsible for load balancing traffic at the global level, across multiple data centers. Some responsibilities for a GTM administrator may include:

• Configuring DNS: This includes setting up DNS zones, records, and views, as well as configuring DNS resolution methods, such as round-robin and weighted round-robin.
• Managing GTM configurations: This includes setting up load balancing methods, such as geographic and priority-based, as well as configuring health monitors to ensure that traffic is only sent to healthy servers.
• Managing high availability and disaster recovery solutions: This includes setting up device groups, failover, and sync-failover configurations to ensure that traffic continues to be served even in the event of a device failure.

ASM

F5 ASM (Application Security Manager) is responsible for securing web applications by protecting them from common attacks, such as SQL injection, cross-site scripting, and cookie poisoning. Some responsibilities for an ASM administrator may include:

• Configuring security policies: This includes setting up security policies that define the types of traffic that are allowed or blocked, as well as configuring security settings, such as intrusion detection and prevention.
• Managing SSL offloading: This includes configuring SSL certificates, private keys, and ciphers, as well as configuring SSL termination and re-encryption.
• Managing high availability and disaster recovery solutions: This includes setting up device groups, failover, and sync-failover configurations to ensure that traffic continues to be served even in the event of a device failure.

APM

F5 APM (Access Policy Manager) is a product that allows administrators to secure and control user access to web-based applications and resources. Some responsibilities for an APM administrator may include:

• Configuring access policies: This includes setting up policies that define the types of users that are allowed to access specific resources, as well as configuring access controls, such as multi-factor authentication and single sign-on.
• Managing user access: This includes configuring user roles and permissions, as well as managing user authentication and authorization.
• Managing remote access: This includes setting up VPN and SSL-VPN connections, as well as configuring remote access policies.
• Managing security: This includes configuring security settings, such as intrusion detection and prevention, as well as implementing security best practices, such as regular security audits and vulnerability assessments.
• Managing high availability and disaster recovery solutions: This includes setting up device groups, failover, and sync-failover configurations to ensure that traffic continues to be served even in the event of a device failure.
• Managing and monitoring the access logs to detect any suspicious activities and also to troubleshoot any issues.
• Managing and configuring the APM's modules such as: Webtop, Webtop portal, Webtop portal customizations, Network access, and Secure browse.
