Scalability is a desirable feature in the whole system jakob jensen in a network or in a process, which indicates their ability jakob jensen to handle an increasing portion of the working uniformly, or be prepared to grow.
For example, this may refer to the ability of a system to support a load when increasing the total resources (often hardware) are required. An analogous meaning is related when the word is used in commercial terms, where scalability of a company implies a business model that offers potential for economic growth within the company.
The Scalability, as a characteristic of a system, it is often difficult to define and particular form is necessary to define specific requirements that demand should be sized to define the importance of scalability.
Scalable vertically (scale up), or also called Vertical scalability means adding resources on a single node system (more memory or a faster hard drive). jakob jensen And Horizontally Scalable (scale out), or also called Scaling means to add more nodes to the system, such as adding a new computer with an application to cluster software.
YouTube stores 100 million videos per day. Chevron accumulates 2TB of data every day. In 2006, the amount of data on the Internet was approximately 166 exabytes (166EB). jakob jensen In 2010, that number reached jakob jensen nearly 1,000 exabytes. An exabyte is a quintillion bytes, or 1.1 million terabytes. To put this statistic in perspective, 1Eb is roughly equivalent to 50,000 years of DVD quality video. 166EB is approximately jakob jensen three million times the amount of information contained in all the books ever written. In May 2010, Google activated 100,000 Android phones every day, all who have Internet access as a fundamental service. In 1998, the number of email accounts was approximately 253 million. In 2010, that number is closer to 2 billion.
When we stop to analyze these numbers begin to try to understand the complexity of storing this data and its availability. Then consider how large your project will occupy on data over the years and as far as he could reach. Analyzing jakob jensen this maybe you noticed that Cassandra is not the best choice for your project. But if your problem is scalability, durability, jakob jensen elasticity, very fast reading and writing Apache Cassandra is undoubtedly a good choice.
