Week 1 Blog Entry
I am Jeff Fackler. I have been in the Air Force for 19 years now. I have only dealt with cloud computing in my past BSIT 375 class. I am a Cyber Systems Operator in the AF, and love my job. For my first blog entry I would like to point out that you can become certified through CompTIA in Cloud Computing Essentials. To do this you can take their exam. What that entails is a 50 question test that is multiple choice. You have 60 Minutes to take the test and you must score above a 720 on the exam in order to pass. It cost $119 to take. The exam covers clouds services from a company perspective. The test validates if you know the business value of cloud computing, cloud types, steps to a successful adoption of the cloud, the impact and changes on IT services management, as well as risks and consequences of cloud computing. If you are interested and would like to look into this certification further, please follow the link below for more information.
Week 2 Blog Entry
As I am more familiar with Network Area Storage, I decided that I would look up some info regarding it and cloud computing. I did a little bit of research on the differences and some comparisons of a NAS and Cloud Computing. Below is the information that I came across that I would like to share. There are some features that are kind of must haves in regards to building NAS as your type of storage for your company.
- Security – Your NAS will be storing confidential company data, consider the use of SSL to protect the Web management interface a bare minimum. Cloud Computing Services have security as a main priority with every service that I have researched.
- Power Consumption – Because your NAS is likely to be switched on 24/7, energy starts becoming more important in the way of environmental impact and your electricity bill. The cloud alleviates this issue, but is normally factored into the cost.
- iSCSI Support – An increasing number of NAS come with iSCSI support, making this a de facto feature. In cloud computing this is not a factor as you will be connecting to all of your storage remotely, which keeps you from having to purchase a certain type of storage.
- Ability to sync/backup to another NAS – Storing a copy of the data with another NAS at another physical location is invaluable in ensuring data survivability. Cloud Computing Services offer assured recovery in the event of a disaster.
- Multi-functional Capabilities – Extra features built into a NAS can be very useful. The availability of FTP services can be used for staging and transferring large files across the Internet – with the right firewall configuration. The ability to host Web files can be used to host internal websites or intranet portals. Cloud Services offer many different capabilities, to include scaleability on the fly which is one of their best features.
- Deduplication – Depending on the compression ratio gained and preferred backup regime, this might be invaluable to some Small/Medium Business.
- On-board, hardware-accelerated encryption – If possible, opt for NAS with on-board encryption support that can perform encryption at much faster speeds. Encryption is the best defense against vendors or business partners simply walking away with one of the companies hard drives. Although not necessarily defined as a feature of Cloud Computing, they do offer Cloud Bursting which replicated the hardware acceleration, as they open up the private cloud to join in the public cloud for processing calculations for the time that “acceleration” is needed.
- Support for syncing with cloud storage – This allows your business to do without configuring a firewall or VPN that is required for NAS-to-NAS backups. With that some cloud-based services have high levels of redundancy, which can reinforce data survivability a second layer of backup for data.
All of these are items to look into if your company is going to be using a NAS or going to a Cloud Service platform. Do you feel like there were any items that I missed? Please feel free to let me know on the discussion board. Thank you.
