Cloud Security is a problem
Cloud computing is still fairly new technology. Like with any new technology that's introduced on them market, it is going to suffer some growing pains. Some of the common challenges of cloud computing includes: Privacy and data security, managing the the cloud computing system, dealing with lock in, and effectively managing the contractual relationships.
Some of the challenges in cloud computing are high priority such as safeguarding valuable information and securing privacy for customers and users. Keeping your software legal and legitimate is also another factor.
There are a variety of different issues with cloud computing; the first problem is just understanding all the details of cloud computing. Another problem is people you work with and use it with don't understand the technology and don't see the point in it.
I found three Cloud Computing magazines you might be interested in. They are; Alltop - Top Cloud Computing News, Cloud Computing Journal and TMC's Cloud Computing Magazine. I hope that you find these choices helpful.
Yes, there are definitely free options available if you want to try out cloud computing for business purposes. Most of the major cloud providers offer free tiers that let you experiment without paying upfront: AWS Free Tier – 12 months of free services (EC2, S3, RDS, etc.) with limited usage, plus some services that are always free. Google Cloud Free Tier – $300 free credits valid for 90 days, plus always-free products like Cloud Functions, Firestore, and Pub/Sub with usage limits. Microsoft Azure Free Account – $200 credits for 30 days and free limited access to services like Azure App Service, Functions, and Storage for 12 months. IBM Cloud – Lite plans with free quotas for databases, AI, and Kubernetes. Oracle Cloud Free Tier – generous always-free services including 2 VMs, block storage, and load balancer. For a small business or startup, these free tiers are usually enough to build prototypes, test applications, or even run small workloads at no cost. Just keep in mind: the “free” part has limits (usage quotas). Once you exceed them, you’ll be billed. So it’s a good idea to monitor usage closely
Any computer website that has cloud computing on it should be able to keep you updated with news about cloud computing technology. I recommend Microsoft.
There is a good explanation of cloud computing at http://www.infoworld.com/d/cloud-computing/what-cloud-computing-really-means-031. I think you can learn most of what you need to know there.
Cloud computing is better then normal grid computing as its cheaper to buy, use and maintain. Cloud computing can offer web hosting also which grid computing can not.
There is no normal cloud computing platform. Cloud computing is a new computer operating system that is becoming popular.
You can either go to: en.wikipedia.org/wiki/Cloud_computing or searchcloudcomputing.techtarget.com/definition/cloud-computing for a full definition of what cloud computing is.
Cloud computing papers are papers that give the basic definition of cloud computing and explain it. Cloud computing is just a way that involves connectivity to the internet.
Cloud computing or grid computing depends on the task at hand. If you want to focus on a single enormous task, then go with grid computing. Cloud computing is more for multitasking.
