You are an Enterprise Architect in a large IT organization. Your organization has deployed applications on a variety of containers such as WLS， WebSphere， and JBoss.  Why would you consider consolidating on a single type of container （instead of mix） ？ （）

• A、 Guarantee of higher application performance and reliability if the transactions are flowing between instances of the same container type.
• B、Easier to build a Shared Services infrastructure that can provide best practices， tools and expertise around HA/Management.... with a single type of container than a mix of multiple types
• C、 You’ll save on hardware costs with a homogenous environment
• D、 It’s a necessary step in our move toward adopting SOA
