The document introduces the WSO2 Microservices Server (MSS) and its features, emphasizing a lightweight, high-performance architecture for building and deploying microservices using Java annotations. It details the core functionalities such as quick development, metrics gathering, and security through JWT tokens, alongside deployment options with Docker and Kubernetes. The MSS aims to enhance developer experience with simple tooling and strong analytics support, positioning itself as a robust alternative in the microservices landscape.

2. Microservices
Architecture
A
method
of
developing
soAware
applica)ons
as
a
suite
of
independently
deployable,
small,
modular
services
in
which
each
service
runs
a
unique
process
and
communicates
through
a
well-­‐defined,
lightweight
mechanism
to
serve
a
business
goal.

Vision
for
Microservices
Server
(MSS)
• Lightweight
&
fast
run)me
• Use
Java
annota)ons
as
a
way
of
defining
microservices
APIs
as
well
as
metrics
• Support
well
known
&
widely
used
methods
such
as
JAXRS
annota)ons
• Provide
simple
ways
to
develop
&
deploy
microservices
• Built-­‐in
Metrics
&
Analy)cs
APIs
with
out
of

box
integra)on
with
WSO2
Data
Analy)cs
Server
(DAS)
• To
be
used
in
the
WSO2
pla]orm
as
a
way
of
replacing
all
admin
services
as
well
as
defining
other
microservices
for
inter-­‐component
interac)ons

41. Pricing
• For
MSS
product
(full
server)
&
MSS
lite
(executable
jar),
pricing
is
same
as
WSO2
AS
based
on
the
number
of
JVMs.
• For
container
based
deployments,
it
will
be
the
same
as
for
any
container
based
deployment
of
WSO2
products
(to
be
announced)
