Comparing Solaris 11 Zones to Solaris 10 Zones
Solaris 10 Whole-Root, Solaris 10 Sparse-Root, Solaris 11, Solaris 11 Immutable Zones
Jeff Victor writes, "Many people have asked whether Oracle Solaris 11 uses sparse-root zones or whole-root zones. I think the best answer is "both and neither, and more" - but that's a wee bit confusing. This blog entry attempts to explain that answer.

First a recap: Solaris 10 introduced the Solaris Zones feature set, way back in 2005. Zones are a form of server virtualization called "OS (Operating System) Virtualization." They improve consolidation ratios by isolating processes from each other so that they cannot interact. Each zone has its own set of users, naming services, and other software components. One of the many advantages is that there is no need for a hypervisor, so there is no performance overhead. Many data centers run tens to hundreds of zones per server!..."

Open source vs. proprietary cloud provider platforms
SearchCloudProvider, June 13th, 2013
"Open source cloud platforms like OpenStack, CloudStack and Eucalyptus offer providers access to a large pool of development resources, quicker updates and no vendor lock-in. While some cloud providers like the idea of building their cloud services on open source software, others prefer the full feature set and integration that a proprietary platform delivers, as well as the comfort of a service-level agreement, or SLA.

The industry remains split on open source vs. proprietary cloud platforms. A recent TechTarget survey found that 22% of 260 cloud providers have adopted OpenStack, while 29% of respondents who aren't using the platform have adopted a proprietary solution..."

Cloud Computing: Concepts, Technology & Architecture
by Thomas Erl & Ricardo Puttini
Juergen Kress writes, "During my holiday I read this book, here is my quote “Cloud Computing: Concepts, Technology & Architecture is an excellent resource for IT professionals and managers who want to learn and understand cloud computing, and who need to select or build cloud systems and solutions. It lays the foundation for cloud concepts, models, technologies and mechanisms. As the book is vendor-neutral, it will remain valid for many years. We will recommend this book to Oracle customers, partners and users for their journey towards cloud computing. This book has the potential to become the basis for a cloud computing manifesto, comparable to what was accomplished with the SOA manifesto."

    SPARC T5-4 Produces World Record Single Server TPC-H @3000GB Benchmark Result
    SPARC T5-4 server with 4 SPARC T5 processors is 2.1 times faster than the IBM Power 780 server with 8 POWER7 processors
    Oracle's SPARC T5-4 server delivered world record single server performance of 409,721 QphH@3000GB with price/performance of $3.94/QphH@3000GB on the TPC-H @3000GB benchmark. This result shows that the 4-chip SPARC T5-4 server is significantly faster than the 8-chip server results from IBM (POWER7 based) and HP (Intel x86 based).

    This result demonstrates a complete data warehouse solution that shows the performance both of individual and concurrent query processing streams, faster loading, and refresh of the data during business operations. The SPARC T5-4 server delivers superior performance and cost efficiency when compared to the IBM POWER7 result...

    SPARC T5-8 Delivers Best Single System SPECjEnterprise2010 Benchmark running WebLogic 12c
    27,843.57 SPECjEnterprise2010 EjOPS
    Oracle produced a world record single-server SPECjEnterprise2010 benchmark result of 27,843.57 SPECjEnterprise2010 EjOPS using one of Oracle's SPARC T5-8 servers for both the application and the database tier.

    • The SPARC T5-8 server ran the Oracle Solaris 11.1 operating system and used Oracle Solaris Zones to consolidate eight Oracle WebLogic application server instances and one database server instance to achieve this result. The IBM system used LPARS and AIX V7.1.

    • This result demonstrated less than 1 second average response times for all SPECjEnterprise2010 transactions and represents JEE 5.0 transactions generated by 227,500 users.

    • The application server used Oracle Fusion Middleware components including the Oracle WebLogic 12.1 application server and Java HotSpot(TM) 64-Bit Server VM on Solaris, version 1.7.0_15. The database server was configured with Oracle Database 11g Release 2.

    • The 8-chip SPARC T5 processor based server is 2.6x faster than the 8-chip IBM POWER7+ processor based server.

    Monitoring per Zone Filesystem activity
    fsstat(1M)
    Solaris 11 added a new at fsstat(1M) monitoring command that provided the ability to view filesystem activity at the VFS layer (ie filesystem independent). This command was available in Solaris 11 Express and the OpenSolaris releases as well.

    In Solaris 11.1 support was added for per Zone and aggregated information so now we can very quickly determine which zone it is that is contributing to the operations...

    Best Practices - Live Migration on Oracle VM Server for SPARC
    By Jeff Savit
    Jeff Savit writes, "Oracle VM Server for SPARC has supported live migration since 2011, providing operational flexibility for customers who need to move a running guest domain between servers. This can be extremely useful, but there's confusion about when it is the right tool to use, when it isn't, and how to best make use of it. This article will discuss some best practices and "do's and don'ts" for live migration..."

    Java Platform Enterprise Edition 7 (Java EE 7)
    Also Java EE 7 Software Development Kit (SDK).
    Oracle and the Java Community Process (JCP) members today the availability of Java Platform, Enterprise Edition 7 (Java EE 7) and the Java EE 7 Software Development Kit (SDK).

    The standard in community-driven enterprise software, Java EE 7 is the result of industry-wide development involving open review, ongoing builds and extensive collaboration between hundreds of engineers from more than 30 companies within the Java Community Process (JCP) and the GlassFish Community.

    Java EE 7 features a scalable infrastructure that facilitates building HTML5 applications by reducing response times through low-latency, bi-directional communication with WebSockets; simplifying data parsing and exchange using industry-standard JSON processing and supporting many more concurrent users through asynchronous RESTful Web Services with JAX-RS 2.0.

    To help further increase developer productivity, Java EE 7 provides a simplified application architecture with a cohesive, integrated platform; reduces boiler-plate code using dependency injection and default resources; broadens the use of annotations to increase efficiency; and enhances application portability with standard RESTful Web Services client support.
