Cloud Computing

Cloud Computing is the course in which they learn about cloud computing software, common set of core techniques, algorithm and design philosophies. Some of these concepts include clouds, MapReduce, key-value/NoSQL stores about C+ Program.
For learning cloud computing, here are few best books in the market.
1. Cloud Computing Concept, Technology and Architecture by Thomas Erl. The book is published by Pearson Education and one of the highest selling book for Cloud Computing.
2. Cloud Computing Principle and paradigm By Rajkumar Buyya and James Broberg.
3. Cloudonomics: The Business Value of Cloud Computing by Joe Weinman.
4. Cloud Computing Design Patterns.
5. Cloud Computing Black Book by Kailash Jayaswal, Donald J. Houde.
6. Cloud Computing Bible Book By Barrie Sosinsky.
7. Cloud Computing From Beginning to End by MR Ray J Rafaels.
8. Cloud Computing: Theory and Practice
by then C. Marinescu.
9. Architecting the Cloud: Design Decisions for Cloud Computing Service Models (SaaS, PaaS, & IaaS) By Michael J Kavis and published by international publisher Wiley.
10. Building the Infrastructure for Cloud Security by Raghuram Yeluri.

In my opinion, cloud security architecture is effective only if the correct defensive implementations are in place. An efficient cloud security architecture should recognize the issues that will arise with security management. The security management addresses these issues with security controls. These controls are put in place to safeguard any weaknesses in the system and reduce the effect of an attack. While there are many types of controls behind a cloud security architecture, they can usually be found in one of the following categories:
Deterrent controls:
These controls are intended to reduce attacks on a cloud system. Much like a warning sign on a fence or a property, deterrent controls typically reduce the threat level by informing potential attackers that there will be adverse consequences for them if they proceed. (Some consider them a subset of preventive controls.)
Preventive controls:
Preventive controls strengthen the system against incidents, generally by reducing if not actually eliminating vulnerabilities. Strong authentication of cloud users, for instance, makes it less likely that unauthorized users can access cloud systems, and more likely that cloud users are positively identified.
Detective controls:
Detective controls are intended to detect and react appropriately to any incidents that occur. In the event of an attack, a detective control will signal the preventative or corrective controls to address the issue. System and network security monitoring, including intrusion detection and prevention arrangements, are typically employed to detect attacks on cloud systems and the supporting communications infrastructure.
Corrective controls:
Corrective controls reduce the consequences of an incident, normally by limiting the damage. They come into effect during or after an incident. Restoring system backups in order to rebuild a compromised system is an example of a corrective control.

There are a number of security and privacy concerns associated with cloud computing.
Multi-tenancy - makes it easier for a hacker to to steal the data of all business customers who share the same cloud database.
Threats of data loss and data leakage -the threat of data leakage increases when employees use their mobile devices to access and share corporate documents via cloud storage services such as DropBox, Box, etc.
Insecure APIs - Most cloud service providers do not pay attention to the security of their APIs which can pose risks to an enterprise data with regards to privacy and data integrity.
Encryption - Most government regulations (HIPAA, PCI) require that data encryption. Although encryption is widely used, it is often implemented poorly. Many companies depend on the cloud provider for encrypting data which means that have control of the key & can access the data anytime.
Key management - Managing and storing these keys in a safe and secure location is of paramount importance when it comes to keeping the entire cloud database safe and secure. Most companies store both encryption and decryption key on the same database which can be detrimental for security.
Scope:
According to the statistics provided by the market research media, the worldwide market for Cloud Computing is likely to grow at a CAGR of 30% to reach US$ 270 billion through the year 2020. Considering the cutting-edge innovations and new industry-specific applications, cloud computing is fast emerging as an essential component of an enterprise IT framework.
Organizations, both big and small have deployed the cloud technology in some suitable capacity. Enterprises need expert IT professionals to work around the cloud. The cloud computing industry requires professionals with adept training and knowledge in both technical and managerial fields. The demand for IT professionals continues to rise at an exponential rate as more and more enterprises adopt cloud computing.

Hello,
Cloud computing is the "in thing" "latest trend" these days. It has taken up the industry by storm. It's very useful particularly to the young entrants who can ill afford to spend money and time and resources for storage devices and associated hardware/ software. There is a big demand for professionals in this field. CMU's Cloud computing course is available online and one can take it without any doubt. However, it is pointed out that similar course is also being offered by many Indian Universities it even institutions working in this field. Many of these are equally capable. Cloud computing is definitely not dangerous for our data. This is because the enterprises offering this service have to make sure that it's confidentially stored with adequate firewalls and robust systems in place. But then Murphy's Law is always there! But frankly speaking it is quite adequately safeguarded and is not dangerous at all.
