Why Akka?
|
|
=========
|
|
|
|
What features can the Akka platform offer, over the competition?
|
|
----------------------------------------------------------------
|
|
|
|
Akka provides scalable real-time transaction processing.
|
|
|
|
Akka is an unified runtime and programming model for:
|
|
|
|
- Scale up (Concurrency)
|
|
- Scale out (Remoting)
|
|
- Fault tolerance
|
|
|
|
One thing to learn and admin, with high cohesion and coherent semantics.
|
|
|
|
Akka is a very scalable piece of software, not only in the context of performance
|
|
but also in the size of applications it is useful for. The core of Akka, akka-actor,
|
|
is very small and easily dropped into an existing project where you need
|
|
asynchronicity and lockless concurrency without hassle.
|
|
|
|
You can choose to include only the parts of akka you need in your application
|
|
and then there's the whole package, the Akka Microkernel, which is a standalone
|
|
container to deploy your Akka application in. With CPUs growing more and more
|
|
cores every cycle, Akka is the alternative that provides outstanding performance
|
|
even if you're only running it on one machine. Akka also supplies a wide array
|
|
of concurrency-paradigms, allowing users to choose the right tool for the
|
|
job.
|
|
|
|
|
|
What's a good use-case for Akka?
|
|
--------------------------------
|
|
|
|
We see Akka being adopted by many large organizations in a big range of industries:
|
|
|
|
- Investment and Merchant Banking
|
|
- Retail
|
|
- Social Media
|
|
- Simulation
|
|
- Gaming and Betting
|
|
- Automobile and Traffic Systems
|
|
- Health Care
|
|
- Data Analytics
|
|
|
|
and much more. Any system with the need for high-throughput and low latency
|
|
is a good candidate for using Akka.
|
|
|
|
Actors let you manage service failures (Supervisors), load management (back-off
|
|
strategies, timeouts and processing-isolation), as well as both horizontal and
|
|
vertical scalability (add more cores and/or add more machines).
|
|
