Over 100 people turned out for our Webcast “A Primer on Oracle SaaS, IaaS and PaaS Options” and as usual there were lots of questions.
We’re happy to make the complete Q and A Chat transcript available.
Q: What’s the difference between “Cloud” and “virtualization?| Do you still have physical servers in the Cloud? can you provide a real working example of a private Cloud implementation?
A: Both terms “Cloud” and “virtualization” are connected. Let’s start defining virtualization, which is a known term but we’ll connect it with Cloud. Virtualization is the creation of a virtual version of a platform, storage device or network resources. In other words, it is software (virtualization software) acting as a layer between a server’s primary OS and the virtual OS allowing the virtual system to access the server’s hardware such as RAM, CPU, etc. As mentioned in the webcast this access makes it possible to manipulate the specs on the virtual device.
Cloud Computing is a style of computing where scalable and elastic IT-enabled capabilities are delivered as a service to external customers using Internet technologies.
How these two terms linked together? It is because a Cloud service provider will not be capable of delivering this flexibility without using virtualization and other techniques to minimize the capital expenditure and offer a true Cloud service.
The Cloud is using physical servers ( this link from Oracle provides a good example are the hardware + software from Oracle leveraging multiple features including virtualization).
This link shows you Google -one of the biggest Cloud service providers- data center where you can see the physical hardware.
A real working example of a private Cloud can be found in in the white paper “The CIO’s Plan V – Oracle E-Business Suite Virtualization” which you can download from our website.
Q: What are some companies currently offering IaaS services?
A: The most famous company offering IaaS is Amazon. Oracle started to offer this service in October 2012 at Oracle OpenWorld. Also IT Convergence is offering IaaS limited to Oracle Technology.
Q: If clients can self-install software even when bound by an IaaS, how do you guarantee the integrity of the computing software can be maintained?
A: This depends on the IaaS service provider but in terms of the service for Infrastructure, the vendors have a clear definition and scope of the service which guarantees the infrastructure and not the application or virtual machines running on top of it.
Q: How does one handle the issue of extreme resource utilization with Oracle products running on virtual machines?
A: If an Oracle product has been certified for virtual machines and that means that Oracle guarantees the deployment will function even in under extreme circumstances and heavy utilization. You can find more information on Oracle’s website in the virtualization section.
Q: What are some current certifications that a systems analyst can attempt to gain a better foundation in Cloud Computing?
A: Oracle has certified multiple products on multiple virtual platforms.
Some resources from Oracle on certifications:
You can also check on My Oracle Support the different certifications to run on multiple Virtualization platforms for your specific Oracle Product.
Q: Does migrating to the Cloud increase or decrease the number of Data Centers a global company needs to run?
A: There are several key metrics when evaluating the use of Cloud. As mentioned in the presentation there are some important questions to consider: Do you need to be flexible on hardware allocation? Do you need managed services? Are you running on standards?
Then the architecture of your Cloud solution might involve multiple Data Centers or not depending on your operations and also on the disaster recovery plan (DRP). In other words, getting into the Cloud does not necessary mean that you will decrease the number of data centers, but for sure your organization will decrease the total cost of ownership (TCO) by decreasing the hardware, network devices and storage.
Q: What are some of the security issues companies currently face as a result of a migration to the Cloud, and how are those issues being addresses?
A: The definition of a Cloud strategy for an organization has multiple discussion points including a big list of benefits and also some risks, which have to be mitigated. One of the biggest challenges is the security and there’s a new definition for it that is “Cloud security”. It is a set of policies, technologies and controls deployed to protect data, applications and the associated infrastructure of Cloud Computing.
The architected solution – whether is full public Cloud or private Cloud or hybrid – needs to be secured and there are many tools available for that. A set of products from Oracle are helping organizations to adopt Cloud Computing ensuring security, privacy and regulatory compliance. For more information you can see what Oracle itself has to say about Cloud Security.
Q: How does a company guarantee redundancy within the Cloud?
A: There are many ways to guarantee redundancy within the Cloud. Your organization can architect a solution using multiple Cloud vendors to reduce a single point of failure but also each vendor provides a service level agreement ensuring up times and disaster recovery plans.
IT Convergence Enterprise Cloud solutions leverage use of two Data Centers, providing a complete DR solution. In the event of an emergency, IT Convergence guarantees your organization will have their environment back online in a matter of hours because ITC’s standard DR solution places production and DR environments in separate data centers. This comprehensive disaster recovery solution comes as a standard part of IT Convergence’s Hosting Services offering.
Q: Can you give specific examples of scripting services and mobile services within PaaS?
A: At this time we are not aware of any PaaS scripting or mobile services.
Q: How do Oracle’s Cloud offerings impact licensing for the E-Business Suite?
A: In terms of licensing Oracle E-Business Suite specifically for the application it remains the same, which is depending on the product but the most common is per name user. The big change is on those web products and also for the database. In this case you have to check your products and the future virtualization setup with the policy from Oracle’s official pricing index.
IT Convergence is planning to continue with its webcast series in 2013 and our full webcast schedule will be announced shortly.
