What is
              Cloud Foundry?

What is the strength of
               “OSS-based PaaS”?


12   1   23
There are several build-
               in OSS “as a Service”!


12   1   23
What are built-in
              “as a Services”?


12   1   23
Pg as a Service!

NoSQL DBs as a
12   1   23
                 Service!
However,



12   1   23
There is a missing
                  service...


12   1   23
That is :



12   1   23
Memcached
                        http://memcached.org/
12   1
         http://www.sixapart.com/labs/memcached/libraries.html
         23
What is memcached?

              •   “Free & open source, high-performance,
                  distributed memory object caching
                  system”
                  quoted from http://memcached.org



              • Very, very widely used component!

12   1   23
Problem

              • No Memcached support in Cloud Foundry

              • The other PaaSes provide memcached-like
                caching service as a Service




12   1   23
IF CF supports
              Memcached as a Service,
                PaaS users can use



12   1   23
Therefore,



12   1   23
We(NTT Com)
                  implemented
              Memcached as a Service!



12   1   23
Available from
         NTTCom Repository
         https://github.com/nttcom/
                 vcap-services

12   1   23
Current
                    implementation
              • Based on Redis as a Service
              • About 1400 LOC including tests
              • Supports:
               • Basic resource restriction
               • Multiple instances
               • can be used from CF apps
12   1   23
Sample Code
              https://gist.github.com/
                      1547175

               Simple count up app

Current Situation

              • Sent Pull request
               • https://github.com/cloudfoundry/vcap-
                  services/pull/15
               • Some users approved our patch
               • However...

12   1   23
No response from
               CloudFoundry
                teams... orz


12   1   23
ToDo


              • SASL supports
              • Configurable parameters in more detail


12   1   23
Summary

              • NTTCom implemented MaaS
                (Memcached as a Service)
              • It can be used from CF apps
              • There are several ToDo, but pending
                because no response from CF DEV teams.
