SSL Offload

Security on the web is much higher profile now than even a few years ago. Secure web traffic by SSL is now the standard for web applications and web sites. Even members of the general public are aware of "ssl encryption" on e-commerce sites.

It's a very CPU-intensive job for servers to encrypt and to decyrpt network traffic. Typically the initial session setup it the most demanding. As a site is migrated to 2048-bit (and higher) SSL keys, a server's "general purpose" CPUs will take a bit hit.

In fact, the usage of the CPU will increase anywhere from 4 to 7 times. If you consider higher keys like 4096-bit ones, a CPU is bound to hit it's limits - at typical traffic volumes.

Certificate Authorities are no longer providing SSL certificates with less than 2048-bit key lengths. The minimum key has gone from 1024 to 2048-bit throughout the entire industry - and it's quickly upgrading.

A10's ADC (Application Delivery Controllers) can handle peaks of high-volume traffic, and can managed secured traffic via powerful hardware that enables them many CPS (Connections per Second).

New customers in a shared web hosting environment might also require SSL certs with higher keys like 4096-bit. The Application Delivery Controller you choose has to be very flexible in order to meet those requirements.

It can be a huge task, having to administer these certificates - particularly when many of the servers need a separate cert. When you move the termination point to an A10 ADC it significantly reduces the cost of operation for managing certs - not to mention less human errors!

Making your A10 Application Delivery Controller the SSl termination point will significantly decrease the cost involved with managing certificates. It also reduces operational human errors.

In addition, your backend servers don't have to be performing CPU-intensive encryption and decryption or setting up network connections that are secure. This greatly decreases demands on your server hardware - as well as the actual number of servers required!

AX Series & Thunder ADCs - With Dedicated SSL Hardware Acceleration

The Thunder and AX Series appliances are powered by the 64-bit ACOS operating system, which provides linear scalability and is designed to get the maximum performance levels from the application and traffic acceleration hardware.

All models have powerful CPUs and support the SSL Offload feature, but select models are available with a range of high-performance, multi-chip SSL acceleration cards that are exceptionally well suited for environments with growing SSL needs.

The new SSL acceleration hardware for the A10 ADCs provide near-parity performance for the upgrade to 2048-bit key lengths, and has the extreme power needed to handle 4096-bit keys at high quality production levels.

4096-Bit SSL Performance

For environments where higher encryption standards are required, the A10 ADCs prove to be the right solution. Even when upgrading to 4096-bit keys, the SSL hardware acceleration cards provide unprecedented performance, making 4096-bit keys viable and cost effective for production use.
