Current your network has a Single Firewall Appliance, Corporate business availability depends largely on IT network availability. Network security, Proxy, VPN, Email applications are being currently implemented with a Firewall. Business also uses ISP failover. Hardware failure of Firewall results in Network Downtime which effects the operational continuity of a Business environment. Any Network Downtime Results to Business revenue Loss, as the complete IT Network and internet connectivity gets disturbed. Also Remote VPN Users who are connected to the Application servers for HO data trasnfer get disconnected which results in productivity loss for them. Network Downtime also Results in Business image loss for Business. Firewall being a very important active component in the IT Setup requires a disaster recovery plan. Current Business Situation
How to ensure N/W availability With High availability or Clustering solution with 2 AnexGATE Firewall Appliances. Firewall Clustering or Firewall Redundancy is the arrangement of 2 or more Firewalls designed & configured either for Availability or for Performance or for both. Firewalls configured in Master-Slave/Hot-Cold/Active- Passive/Primary-Backup mode, ensures High Availability of N/W. So incase the primary Firewall fails, the complete network can be automatically diverted to the secondary firewall thus ensuring no business downtime /loss.
Working of H/A Solution One Firewall in Cluster is configured as Primary/Master/Active. Redundancy based protocol VRRP is used to detect failure. Detection is based on Heartbeats. Heartbeats are token messages that Firewall sends periodically to each other. If Primary stops Heartbeats, VRRP assumes Primary is not Available. Subsequently VRRP selects the Secondary/Slave/Passive Firewall to become new Primary. The prevalent Primary Firewall owns a Virtual IP. This Virtual IP is the Gateway for Peers in the N/W.
When Primary appliance Fails Secondary takes over.
Firewall in Load balancing The other approach in Firewall Clustering is Multi-Primary or Load Balancing mode.This configuration ensures Performance as well as Availability. N/W Traffic Flow can be evenly distributed. This results in Performance. Also in case of Failure, Secondary Firewall takes over all the N/W traffic management until Primary Firewall is restored/revived. This Scenario is particularly useful in Sudden High peak requirements of network where Network load needs to be shared and ensure performance for applications like Trading, ERP, CRM or Emails.
How to avoid Business downtime with H/A 1.H/A ensures almost zero Downtime of your Business Network. 2.As a failure of any single Firewall Device involved in H/A design is transparent to the N/W traffic. 3.In effect, the N/W stays unaffected in the event of failure of any single Firewall without loss of packets, sessions and more importantly security. 4.H/A Solution Ensures that your IT infrastructure Runs smoothly without any downtime. Thus ensuring your instant ROI.
Business Benefits of H/A Solution Technical Benefits of H/A Design: Higher Bandwidth Throughput Smaller Latency Lesser Bottlenecks Higher Mean-Up Time Higher Performance Higher Availability More frequent Security Updates & Patches Business Benefits of H/A Design: Almost Zero Business Downtime Improved Productivity of N/W Lesser Security threats Improved N/W Efficiency Resilient IT infrastructure and Business productivity
