caGrid 2.0 December 2013

What is caGrid 2.0??? Provides a patch for caGrid 1.x to support SHA2 OSGi implementation of WSRF on the new technical stack. – Provides foundation of migrating caGrid 1.x services to new technical stack. caGrid 1.x Services migrated to new technical stack – Not all services were migrated. – Secure services that need to support two endpoints in the same JVM were migrated. – Services that were not migrated will be migrated as part of caGrid 2.1 or deprecated. 2

caGrid 2.0 Technical Stack Java 7 Spring OSGi – A module system and service platform for the Java programming language that implements a complete and dynamic component model Apache Camel – is a rule-based routing and mediation engine which provides a Java object-based implementation of the Enterprise Integration Patterns using an API (or declarative Java Domain Specific Language) to configure routing and mediation rules. Apache Service Mix – OSGi powered Enterprise Service Bus (ESB) Apache CXF – Apache CXF is an open source services framework. CXF helps you build and develop services using frontend programming APIs, like JAX-WS and JAX-RS. These services can speak a variety of protocols such as SOAP, XML/HTTP, RESTful HTTP, or CORBA and work over a variety of transports such as HTTP, JMS or JBI. 3

What caGrid 2.x is Not GAARDS UI – GAARDS UI has not been migrated, existing GAARDS UI is backwards compatible. Introduce – Introduce has not been migrated. – We plan to develop Maven Archetypes that will create service skeletons for new projects Client API – caGrid 1.x java client APIs were not migrated. – caGrid 1.x java clients will continue to work. – New client APIs can be generated using Apache CXF. 5

Moving to caGrid 2.0 Existing 1.x grid services with SHA-1 host certificates will continue to work normally. When their host certificates expire, they will need to replace a single JAR file in their service when they install a SHA-2 host certificate. Development teams using Introduce may continue to, and will have to swap in a replacement JAR after service generation to support SHA-2. Development teams who wish to build WS or Rest web services that interact with caGrid 2.0 may do so in the tool of their choice (e.g. Eclipse, IntelliJ). Given the state of languages and tools to natively support this, no tooling is provided to support this development. 6

Both JBoss and Tomcat 5.5 are falling off Tech Stack. Additional upgrade to move patched services away from Globus is needed.

(Absence of) Tooling for caGrid 2.0 Given the evolution of software development tooling since caGrid 1.0 was released, we do not envision providing tooling (e.g. Introduce 2.0): Java language now supports native annotations to build (for instance) REST interfaces caGrid 2.0 SOA web services are backwards compatible to Globus, but are not Globus services, meaning that it’s possible to build clients and services in other languages that interoperate with the standards and don’t require the client JARs for all interactions Many capabilities were not brought forward into 2.0 (e.g. data services, metadata) but are supported through backwards compatibility. 9

Migration Path for Tools/Sub-projects caGrid Transfer “Service” – Introduce extension developed to support out-of-band data transmission, overcoming a limitation of Axis 1.2 used by Globus Will continue to work through backwards compatibility New, modern options are available if using the caGrid 2.0 approach, but one will not be prescribed 10

What caGrid 1.x Users must do to use caGrid 2.0 Services and Clients do not need to do anything: –caGrid 2.0 services are backwards compatible with caGrid 1.x clients and services –Once the Production Grid is upgraded, services will advertise as they always have 19

What caGrid 1.4 Services must do to support SHA-2 They need not do anything until their SHA-1 certificate expires. When it does: Shutdown the container (JBoss or Tomcat) Patch your caGrid 1.4 service to support SHA-2 Launch the GAARDS-UI –Change your target grid to use the SHA-2 endpoint –“Renew” their existing host certificate –SHA-1 certificates are replaced with a SHA-2 certificates –Replace the deployed SHA-1 cert with new SHA-2 cert Restart the service 20
