You Are Not Even Wrong About the Cloud - Part 1

Many years ago, I read an article in The New Yorker about a math expert who was working as one of the early quants on Wall Street. One phrase from that article has become a part of my vocabulary – “You are not even wrong”. By this, the mathematician meant that the person was so far off base on a topic as to not even qualify as being wrong – it’s like they had left the universe of correct and incorrect on a certain topic.

I have used it over the years as a sarcastic description of some opinion I felt was on the far side of clueless. But, in reality, the description is not just an ultimate putdown of sorts. This phrase can apply to any ideas which don’t really apply to a particular scenario. The person expressing the opinion is not necessarily unintelligent, or even uninformed. They are just playing on the wrong field.

I’ve been product manager for the Oracle Database Cloud for the past 3 years, and I find that this situation is wildly common when people talk about Cloud computing. Seemingly everyone is excited about the possibilities of the Cloud, but the overwhelming majority of people are looking at this technology area from an inappropriate viewpoint.

Put simply, most believe the Cloud is magic. And we all know there is no magic technology – even a great advance like Exadata is a result of a bunch of good decisions implemented well.

The problem lies in something I refer to as the orthogonal nature of costs and benefits. When two terms are orthogonal, there is no statistical relationship between them. In the same way, there are important facets of Cloud computing where the costs and benefits stem from different places – places which are rarely united in a single world view.

This blog is the first of five parts. In the next three parts (with the first of these three parts here), I will discuss three prominent areas of orthogonal costs and benefits, which will help you to understand how to properly evaluate the what, when and hows of Cloud computing for your particular organization. The final part will be a general prescription on how to move to the Cloud to maximize benefits and minimize both problems and disappointments.

Accelerating Your Journey to Self-Service IT with Technology Solutions from Oracle and Partners

At the Oracle Open World 2013, I was really pleased to see many Oracle customers sharing their story of accelerating their journey to Self-Service IT or private cloud leveraging the technology solutions from Oracle and partners.

The Oracle Enterprise Manager General session at Oracle Open World 2013 highlighted the efforts of everyday heroes who are driving their IT organizations’ journeys to a more efficient and agile IT. These heroes - 5 Oracle ACEs and 2 other enterprise Manager customers , shared their experiences in deploying and managing large-footprint Oracle stack environments encompassing Oracle Applications, Oracle Fusion Middleware, Oracle Database, and Oracle engineered systems.

The general session also covered Oracle Enterprise Manager’s own journey as a product in this context and also gave a sneak preview of what’s to come.

Many other customers, for example, Bank of America, Norwey's NAV, Mercy Hospital shared their experience during their journey to private cloud and offering Database as a Service or Middleware as a Service via a self-service portal.

Many partners showcased their private cloud solutions and announced new products at Oracle Open World. Dell announced integration of their Open Manage solution with Oracle Enterprise Manager during Michael Dell's keynote.

 EMC announced their new Oracle Enterprise Manager plug-in for their storage during Jeremy Burton's keynote .


Another key highlight for me was the sessions from Oracle user group members on Sunday, September 22nd. Attendance, engagement and interaction during these sessions were really amazing.

If you missed these sessions, want to review what you learned, or spread the knowledge to others, now you can download most of the sessions presented at Oracle OpenWorld. There are two ways to access the sessions for download (or online review):

  1. Directly through Content Catalog
  2. Indirectly through Schedule Builder to Content Catalog (registered attendees only)

In addition , you can learn more about accelerating your journey to self-service IT by going Zero to Cloud resource page.

Oracle and Microsoft: Partners in the Enterprise Cloud

Back in late June, Oracle and Microsoft announced a new partnership designed to help customers embrace cloud computing by providing greater choice and flexibility when deploying Oracle software. As an extension of its commitment to support multiple platforms, Oracle would certify and support Oracle applications, middleware, database, Java, and Oracle Linux on Windows Server Hyper-V and Windows Azure. Microsoft would offer Java, Oracle Database, and Oracle WebLogic Server to Windows Azure customers. Also, Oracle would offer Oracle Linux to Windows Azure customers. You can review all key elements of the partnership announcement by reading my blog post about it or the press release. Whether you’re in IT, a software industry analyst, or just a techie like me, you knew this was big news.

Now fast forward just a few short months and here comes more good news. Today at Oracle OpenWorld 2013, it was announced that Oracle software including Java, Oracle Database, and Oracle WebLogic Server is now available for preview in Windows Azure. During his partner keynote presentation, Brad Anderson, Microsoft’s Corporate VP of Cloud and Enterprise Engineering, discussed the benefits of being able to deploy and run Oracle’s mission critical software on a Microsoft-based public, private, or hybrid cloud. There was even a demo of how easy it was to deploy Oracle software using pre-configured images from the Windows Azure image gallery. The full list of available Oracle software images is available here

Plug into the Cloud

With the latest release, Oracle Database 12c provides tremendous new capability to enable cloud computing. A new architecture enables greatly simplified database consolidation with no changes to your applications. This new architecture uses a new option, Oracle Multitenant, allowing you to “plug into the cloud” with a multitenant container database that can hold one to many pluggable databases. This greatly increases scalability and server utilization, allowing you to manage many databases as one, all while retaining the complete isolation of separate databases, without changing any application code or access rights.

Each application can then have its own dedicated pluggable database, to ensure complete data isolation and the resource prioritization of separate workloads. Each pluggable database is plugged in to a multitenant container database (CDB), so an administrator only has to deal with administering and managing the one CDB, literally providing the ability to “manage many as one”! This makes it easy to consolidate multiple databases onto private clouds without changing any applications, and still be in complete control of all resources.

This new architecture is designed for cloud, provides efficient consolidation, with rapid provisioning and cloning of databases, along with easier and faster upgrades and patching. With Oracle Multitenant you can quickly and easily plug into the cloud!

Attend the Webcast to learn more about Oracle Database 12c's new multitenant architecture. Be the first to learn how to:

  • Simplify database consolidation
  • Automatically compress and tier data
  • Improve application continuity
  • Redact sensitive data

    Scenes From the First OTN Developer Day for Cloud Application Developers

    Yesterday we held our first OTN Developer Day for Cloud Application Developers and what a day it was.  It was standing room only as we had a packed room of developers at this free, live event at the Oracle Conference Center in Redwood Shores. The developers who attended yesterday's event got to hear and see firsthand how Oracle Cloud Platform Services make developing and deploying enterprise-grade business applications in the cloud faster and easier than ever before.

    The day included service overview presentations by Oracle Cloud product managers, but the bulk of the time was spent doing hands-on exercises with the Java Cloud Service and Database Cloud Service. All in all, it was a great event and we look forward to running more OTN Developer Days for Cloud Application Developers in the future. Stay tuned. In the meantime, here's a couple of pictures from the event...enjoy!

    The presentations from the event are all available for downloaded here. To learn more about Oracle Cloud, go to oracle.com/cloud. If you want to take Oracle Cloud Platform Services for a spin on your own, go to cloud.oracle.com and sign up for a 30-day free trial.

    The APEX of Business Value… or: the Business Value of APEX? Cloud takes Oracle APEX to new heights!

    This blog entry has been re-posted with permission from the author, Lucas Jellema.

    The attraction of APEX has increased tremendously with the recent launch of the Oracle Cloud. APEX already supported departmental development and deployment of business applications with minimal involvement from the IT department (only a database needed be made available). Positioned as the ideal replacement for MS Access, APEX probably has managed better to capture the eye of developers and was used for enterprise application development at least as much as for the kind of tactical applications that Oracle strategically positioned it for.

    With APEX as PaaS & DevaaS from the Oracle Cloud, a leap is made to a much higher level of business value. Now the IT department is not even needed to make infrastructure available with a database running  on it. All the business needs is a credit card. And the business application that is developed, managed and used from the cloud through a standard browser can now just as easily be accessed by users from around the world as by users from the business department itself. As a bonus – the development of the APEX application is also done in the cloud – with no special demands on the location or the enterprise access privileges of the developers.

    To sum it up: APEX from Oracle Cloud Database Service

    • get the development environment up and running in minutes
    • no involvement from the internal IT department required (no for infrastructure, not for platform and not for development)
    • superior availability and scalability is offered by Oracle
    • users from anywhere in the world can be invited to access the application
    • developers from anywhere in the world can participate in creating and maintaining the application

    In addition: because the Oracle Cloud platform is the same as the on-premise platform, you can still decide to move the APEX application between the cloud and the local environment – and back again.

    image

    The REST-ful services that are available through APEX allow programmatic interaction with the database under the APEX application. That means that this database can be synchronized with on premise databases or data stores in (other) clouds. Through the Oracle Cloud Messaging Service, the APEX application can easily enter into asynchronous conversations with other APEX applications, Fusion Middleware applications (ADF, SOA, BPM) and any other type of REST-enabled application.

    In my opinion, now, for the first time perhaps, APEX offers the attraction to the business that has been suggested before: because of the cloud, all the business needs is  a credit card (a budget of $175 per month), an internet-connection and a browser. Not like before, with a PC hidden under a desk or a database running somewhere in the data center. No matter how unattended: equipment is needed, power is consumed, the database needs to be kept running and if Oracle Database XE does not suffice, software licenses are required as well. And this set up always has a security challenge associated with it. The cloud fee for the Oracle Cloud Database Service includes infrastructure, power, licenses, availability, platform upgrades, a collection of reusable application components and the development and runtime environments containing the APEX platform.

    image

    Of course this means that only business departments can move quickly without having to convince their IT colleagues to move along – it also means that small organizations that do no even have IT colleagues can do the same. Getting tailored applications or applications up and running to get in touch with users and customers all over the world is now within easy reach for small outfits – without any investment.

    My misunderstanding

    For a long time, I was under the impression that the essence of APEX was that the business could create applications themselves – meaning that business ‘people’ would actually go into APEX to create the application. And to me APEX was for too much of a developers’ tool to see that happen – apart from the odd business analyst who missed her calling as an IT developer. Having looked at various other cloud based development offerings – including Force.com, Mendix, WaveMaker, WorkXpress, OrangeScape, Caspio and Cordys- I have come to realize my mistake. All these platforms are positioned for ‘the business’ but require a fair amount of coding and technical expertise. However, they make the business happy nevertheless, because they allow the  business to completely circumvent the IT department. That is the essence. Not having to go through the red tape, not having to wait for IT staff who (justifiably) need weeks or months to provide an environment, not having to deal with administrators (again, justifiably) refusing to take on that ‘strange environment. Being able to think of a some initiative and turn into action right away. The business does not have to build the application – it can easily hire some external developers or even that nerdy boy next doors. They can get started, get an application up and running and invite users in – especially external users such as customers.

    They will worry later about upgrades and life cycle management and integration. To get applications up and running quickly and start turning ideas into action and results rightaway. That is the key selling point for all these cloud offerings, including APEX from the Cloud. And it is a compelling story. For APEX probably even more so than for the others. While I consider APEX a somewhat proprietary framework compared with ‘regular’ Java/JEE web development (or even .NET and PHP  development), it is still far more open than most cloud environments. APEX is SQL and PL/SQL based – nothing special about those languages – and can run just as easily on site as in the cloud. It has been around since 2004 (that is not including several predecessors that fed straight into APEX) so it can be considered pretty mature. Oracle as a company seems pretty stable – so investments in its technology are bound to last for some time to come.

    By the way: neither APEX nor the other Cloud DevaaS offerings are targeted at creating applications with enormous life times. They fit into a trend of agile development and rapid life cycle management, with fairly light weight user interfaces that quickly adapt to taste, technology trends and functional requirements and that are easily replaced.image

    APEX and ADF – a match made in heaven?! (or at least in the sky)

    Note that using APEX only for cloud based database with REST-ful Services is also a perfectly viable scenario: any UI – mobile or browser based – capable of consuming REST-ful services can be created against such a business tier. Creating an ADF Mobile application for example that runs aginst REST-ful services is a best practice for mobile development. Such REST-ful services can be consumed from any service provider – including the Cloud based APEX powered REST-ful services running against the Oracle Cloud Database Service!

    The ADF Mobile architecture overview can easily be morphed to fit the APEX services in – allowing for a cloud based mobile app:

    PaaS, DBaaS and the Oracle Database Cloud Service

    As with many widely hyped areas, there is much more variation within the broad spectrum of products referred to as “Cloud” that is immediately apparent. This variation is evident in one of the key misunderstandings about the Oracle Database Cloud Service.

    People could be forgiven for thinking that the Database Cloud Service was a Database-as-a-Service (DBaaS), but this is actually not true. The Database Cloud Service is a Platform-as-a-Service, which presents a different user and developer interface and has a different set of qualities.

    A good way to think about the difference between these two varieties of Cloud offerings is that you, the customer, have to deal with things at the level of the offering, but not for anything below it. In practice, this means that you do not have to deal with hardware or system software, including installation and maintenance, for DBaaS. You also do not have much control over configuration of these options.

    For PaaS, you don’t have to deal with hardware, system software, or database software – and also do not have control over these levels in the stack. So you cannot modify configuration parameters for the database with the Database Cloud Service – your interface is through SQL and PL/SQL, with Application Express, included in the Database Cloud Service, or through JDBC for Java apps running in the Java Cloud Service, or through RESTful Web Services.

    You will notice what is not mentioned there – SQL*Net. You cannot access your Oracle Database Cloud Service by changing an entry in the TNSNames file and using SQL*Net. So the effort involved in migrating an existing Oracle Database in your data center to the Database Cloud Service may be prohibitive.

    The good news is that Application Express and the RESTful Web Services wizard in the Database Cloud Service allow you to develop new applications very quickly, and, of course, the provisioning of the entire Database Cloud Service takes only minutes.
