SOA is Dead. Long Live Services.
Popularized in 2003, the SOA movement took enterprise by storm.
In the last decade, many things have changed including approaches, tools, platforms and goals.
Unfortunately, many organizations have failed to update their SOA program and are now losing productivity and opportunity.

API’s Rule
With the move to ‘simple services’, the ‘remote API’ was born.
Less emphasis service registries (UDDI) More emphasis on publishing developer documentation for API
“If you make it easy, developers will come.”

Light-Weight Envelopes Won
Despite all of the work to create SOAP and the WS-* specifications, they lost the battle.
Light-weight services won because they’re simple. They ride on HTTP. They usually use JSON. They’re usually RESTful, but not always.

Open Source Dominates
Companies like Facebook, Google, Twitter and LinkedIn all face massive scale. They’ve all written next-gen SOA toolkits which they’ve contributed to open source.
“Commercial-only licenses” are rare in Next-Gen. Open source dominates. These solutions are often more
sophisticated than the commercial offerings.

From Service Management to API Management
Developers still need to instrument their services, define SLA’s, throttle traffic, set quotas, etc.
Mashery, Apigee, Layer 7 and others offer API Management Systems.
New open source tools hitting the market:

The use ESB is minimized
The Enterprise Service Bus (ESB) is still used in enterprise shops for hairy integration problems, especially where adapters to legacy systems are required.
There’s less emphasis on the ESB. When needed, open source solutions like Mule and Fuse are used even in massively scalable, highly available scenarios.
New services are put in a light-weight container like Apache TomCat.

New Services exist in PaaS and IaaS
Many SOA programs have failed to release platform and infrastructure services!

New SOA resides on PaaS and IaaS
The “as-a-Service” model is now in full swing with Platform-as-a-Service and Infrastructure-as-a-Service.
Last generation application servers are no longer the preferred model for building and running services.
Light-weight containers running on an elastic infrastructure where SLA’s are tied to monitors and auto-scale are the new model.

A Renewed Focus on SLA’s
Modern service frameworks emphasize SLA’s by providing new features
Avoid cascading failures Monitor with feedback loops.

Resilience is your friend
Complex apps have lots of service dependencies.
Use fail fast techniques: Time-out calls that take
longer than defined thresholds.
Graceful degradation Trip a circuit-breaker Perform fallback logic Monitor metrics and
configuration change in near real-time.

An application that depends on 30 services that each have 99.99% uptime we get: 99.9930 = 99.7% uptime

It’s about the Business
API’s have moved beyond I.T. and are now a business asset
Enable partners and affiliates to do “self-service integration” Find new, unanticipated channel opportunities
“The API is the new BizDev”
