The author’s thesis in the article was describing a product named DynamoDB that was released by the big well known company Amazon. The author describes the database service DynamoDB as being speedy and scalable, and that it’s designed for web applications. The author goes on about DynamoDB by saying it addresses the needs of today’s Web-based apps, which often face challenges with increase in traffic ( how many users at once are using it), number of users, and data. He also says that DynamoDB gives its users the database capacity they need and allows them to fill up that capacity as needed, without requiring any administration, any special skills, new equipment or software. It’s been all taken care of by Amazon for the users. In the article, the author wrote that the Chief Technology Officer of Amazon Werner Vogels said “The service automatically spreads data and traffic across multiple servers to meet the capacity requirements as requested by a customer. Amazon uses Solid State Drives (SSDs) to store data and enhance performance.” Which is a description of some the capabilities of DynamoDB. The author says that you can create a new Amazon DynamoDB database table , and scale capacity up or down as needed without taking the database offline. The author adds on saying although customers have no database administrative duties to perform, they could still monitor resource utilization and performance metrics, and it’s all done through the AWS Management console. Some other features about DynamoDB could include: built-in fault tolerance, automatically replicated data, cryptographic security methods, intgeration with Amazon CloudWatch as well as integration with Amazon Elastic MapReduce, which allows business to perform analytics of large datasets. The author says that with EC2, customers can pay for what they use. The nice thing is that new customers can try DynamoDB for free, receiving 100 MB of free storage with 5 writes/second and 10 reads /second of ongoing through capcaity. As for the pricing, the Data Storage is priced at $1 per GB/month. Users are also charged for data “in” and “out” transfer rates, mainly the data transferred into and out of Amazon DynamoDB. That was pretty much it for the article.
First of all I am grateful to your blog website and I am grateful for the students efforts and yours as well to make the blog website so much educational. I learned from my friends comments that if you are interested in becoming a web developer, the types of services like DynamoDB that is offered by Amazon is a perfect way of investing developing skills into. Developers could make a lot of money depending on what they specialize in. So investing time and skills into building up cloud computing software and services would be great, and you will be able to generate revenue in millions of dollars. You just have to be smart about it, and understand how it’s operated. This was a great class, thanks a lot for everything, and we will keep in touch in the future hopefully. For the first time I feel like I have real colleagues including you that I could share information with and interact with on a professional level. It gave me more confidence in understanding how to deal in the information technology world.
