Hybrid Cloud – The Pros and Cons

With the advent of cloud-based computing, there have been many debates about which type of cloud environment is best.  Some maintain nothing beats a private cloud, others say a public cloud shares resources better, and there are more people who say a hybrid cloud solutions for small business environment is best.  In order to compare the benefits of the three or even just to list the pros and cons of a hybrid, we really need to understand all three types. A private cloud is one created for and used by a single group or business enterprise.  Private clouds are usually hosted on-site.  It affords its users better control of stored data and their locations, resource allocation and flexibility.  These advantages though come at a price that some companies may not be able to afford.  Private clouds require a lot of expensive hardware and software to set-up, and its maintenance would require hiring the services of IT people with specialized skills.  People at the Cloud Security Alliance will have a better idea of the skills it takes. A public cloud on, on the other hand, is set up by cloud services or cloud solution providers.  These companies spend lots of money building a cloud that offers data storage, applications and IT functions to the public.  Its main advantages for the user include not having to invest on expensive hardware and software, pay-per-use or pay-as-you-go modes of charging, relative flexibility, ease of use, and remote access.  Its main disadvantages include less control over resource allocation, fewer options for customization and a bit less security. Hybrid clouds deploy data and computing functions in both local and private clouds.  As such, hybrid cloud solutions possess some of the advantages and disadvantages of both public and private clouds.  Capital expenditures would not be as much as the requirement for a private network, but it will be required.  Data on public clouds will not be as secure, and those on private networks will be only enjoy greater security at a greater cost.  So what makes hybrid cloud solutions better?  Their being hybrid.  It allows businesses to choose which processes and data warrant higher levels of security at greater cost, and which ones should prioritize cost savings. That being said, there is no one-size-fits-all approach to this.  It’s hard to imagine a nation’s spy agency, for example, using a public cloud.  For most businesses, a hybrid cloud...

Netapp Ottawa On Dealing With Cloud Storage Security Issues

A majority of business organizations now use cloud storage solutions, such as those offered by companies like Netapp Ottawa.  These organizations have dipped their toes into the cloud storage environment despite concerns about security and data privacy.  To be quite candid, security improvement measures implemented by cloud storage service providers have done a lot to allay the fears of their clients. Demand for even more cloud storage space has continued to grow despite all the challenges faced by both users and the cloud storage providers.  To handle the data administration more effectively Netapp Ottawa storage virtualization has been utilized. Organizations such as the Cloud Security Alliance believe that clients of cloud storage solution providers can do a lot to improve data security on the cloud.  Here are some steps you can take to make the data you have stored in the cloud a lot more secure: a)       Pick a storage vendor that uses the “zero Knowledge” approach to cloud data storage.  Under this system all data stored in the cloud is encrypted.  You and whoever you grant access to, are given decryption keys which you use whenever you download stored data.  Data stored in the cloud is then kept away from the prying eyes of outsiders.  It is important that you share data to outsiders only after they are downloaded.  Sharing data in the cloud presents opportunities to attack the decryption key b)       It is better to choose cloud storage service providers from your own country, and whose servers are physically located locally as well.  The laws, rules and regulations of your country can more effectively protect your interests when dealing with local providers. c)       Choose a cloud storage vendor who has a good business track record, much like Netapp Kanata.  Remember that you will be entrusting valuable, sometimes proprietary, data with them. d)       Read the fine print in the service contract.  Pay particular attention to cloud storage vendor accountabilities in case of data loss. e)       Consider using a hybrid cloud approach where the most critical pieces of data are store in physical networks which afford you greater control. f)         Increase the security awareness of your staff.  Most cases of security breaches come from improper safeguarding of passwords and keys. Consider using Netapp Kanata storage solutions.  All it takes is a...
