At present, there are various technologies that have transformed different aspects of our life. This includes the way we work, run businesses, interact with each other, and so on. One such flourishing and in-demand technology is cloud computing, which is revolutionizing the way businesses and organizations are running their operations.
In this article, we will introduce you briefly to cloud computing and talk about one of the best cloud services providers, AWS. Also, you will learn about various Amazon Web Services, their applications, and the key advantages and disadvantages of using Amazon Web Services. So, let us begin with a quick overview of cloud computing.
What is Cloud Computing?
Not so long ago, businesses and companies had to use traditional computing, i.e., they had to establish their IT infrastructure to store their digital assets and host applications. Cloud computing has, however, eliminating the need for establishing and maintaining physical data centers and servers. Cloud services allow businesses to store their data on a remote server and then access it via the internet.
Apart from storing and making data easily accessible, cloud computing can do much more. We can define cloud computing as on-demand access to computing services, such as storage, development tools, physical and virtual servers, networking capabilities, applications, and so forth, via the internet hosted at a remote data center. A cloud services provider (CSP) offers these computing resources on an as-needed basis.
What is AWS?
Amazon Web Services is a widely used cloud platform developed by Amazon that offers more than 200 services from data centers spread across the globe. From the fastest-growing start-ups to government agencies and large organizations, numerous organizations and individuals use AWS to make their businesses more productive.
This cloud platform is a combination of Infrastructure as a service (IaaS), Platform as a Service (PaaS), and packaged Software as a Service (SaaS) offerings. It serves millions of customers in more than 190 countries and is used by many reputed companies, like Netflix, Twitter, ESPN, Adobe, Instagram, Pinterest, Dropbox, and LinkedIn.
History of AWS
Back in the year 2002, Amazon Web Services stepped into the market with the aim of selling its unused infrastructure via IaaS. Amazon launched Simple Queue Service (SQS), the first service available in AWS, in 2004. In the year 2006, Amazon relaunched Amazon Web Services with the release of two new services - S3 and EC2, along with SQS.
Later, it released multiple offerings, like VPC in 2009, Route 53 and SNS in 2010, and Elastic Beanstalk in 2011. Later in 2012, Amazon organized several big events with the intent to collect customer feedback, discuss new trends and technologies, and announce its new products. Some major events hosted by Amazon are:
- re: Invent
- re: Inforce
- re: Mars
In April 2013, Amazon started its certification program intended for software engineers having skills in cloud computing. Amazon then launched Amazon Partner Network (APN) in 2014.
By 2016, it surpassed the revenue target of $10 billion and launched Snowball and Snowmobile in the same year. Later in 2018, Amazon introduced new certifications that featured machine learning and artificial intelligence. In the following year, Amazon Web Services offered around 100 fully-featured services, and by 2021, it provided more than 200 products and services.
