ASA/PIX: Load balancing between two ISP-options
VERSION 7
Is it possible to load balance between two ISP links?
Does the ASA support PBR (Policy Based Routing )?
Does the ASA support secondary IP address on interfaces?
What other options do we have?
SLA RouteTracking
PBR on the router outside the firewall
Allowing outbound via ISP1 and inbound via ISP2
Allowing internet access via ISP1 and L2L vpn via ISP2

Applications that use failover clustering may require special coding to ensure that the failover process is transparent to the user when a failure occurs, and that the application is still available. For example, if you place time-outs and retries in the code used to save data to the database, you can ensure that the transaction will complete when the failover

There are three main options for failover operations for Hyper-V replication:Planned failover, as the name implies, is a pre-determined plan to fail over. This approach needs to meet two prerequisites: The virtual machine must be shut down before the initial failover, the replication host must also enable replication, and allow replication from the replication ho

The most outstanding performance of Oracle RAC clusters is high availability, which mainly includes load balance and failover. These technologies enable single point of failure (spof) to prevent normal access to the database by client applications, and load balancing between nodes by creating a service. This article describes the Oracle failover test in the Oracle 10g RAC environment.The following are some

The basic idea of dynamic planning is to break down the problem to be solved into several subproblems, first solve the subproblems, and save the solutions to these subproblems, if you need to solve these subproblems in the future, you can directly retrieve these computed solutions without repeated operations. You can use the table Filli

The ISP is the abbreviation for Image Signal Processor, which is the graphics signal processor. DSP is the abbreviation of digital Signal Processor, also known as the signal processor.
