About Web Sessions
Use Terracotta's fast, reliable web sessions plugin to get the scalability benefits of a stateless web
architecture without overloading your database or rewriting your application. Terracotta for Sessions works with your
favorite web framework and your own custom session objects.
Easy Setup
Terracotta for Sessions is simple to use and is a good fit for a wide range of use cases from departmental
applications to large scale web and eCommerce sites.
Sessions Visibility
See the performance of your entire application cluster at a glance. Also browse the live contents of user sessions
for easy debugging and problem resolution.
Terracotta makes it easy to configure and optimize your sessions and watch the performance boost you're getting
in real time
Scale
Adding additional servers to the application tier is the most effective way to increase capacity. High availability
for sessions at scale is critical to increasing application throughput without downtime or disrupting the customer
experience.
High Performance and High Availability
Get high availability for your session data without sacrificing application performance or punishing your database.
By storing session data on disk, Terracotta for Sessions ensures session data is always available, even in the event of
server failure or restarts.
In-Memory Speed
Terracotta dynamically partitions and optimizes the locality of user session data to provide coherent and reliable access to hot
sessions at memory speed. This architecture yields very high application throughput and very low session access latency, no matter how
many application servers and concurrent users you have.
Capacity on Demand
The Terracotta Server Array enables you to write a simple web application that can scale as needed. Add application
servers on demand for increased capacity without sacrificing session correctness or overloading your database.
Coherent
Terracotta session data is always guaranteed to be coherent, consistent, and up-to-date. This ensures that your
customers' experience is unaffected when they are routed to different application servers in the event of server
failure or restarts.
Efficient
Terracotta keeps only the locally active session data in memory and sends only the changed data over the network when
sessions are updated. This efficient use of memory and network resources enables Terracotta to outperform competitive
solutions.
Broad Container Support
Terracotta for Sessions works with most major application servers and a wide range of popular web frameworks.
