How big companies got benefit from AWS.

What is cloud computing?

Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider.

Types of Cloud computing services-

• Infrastructure as a Service (IaaS). IaaS provides users access to raw computing resources such processing power, data storage capacity, and networking, in the context of a secure data center.
• Platform as a Service (PaaS). Geared toward software development teams, PaaS offerings provide computing and storage infrastructure and also a development platform layer, with components such as web servers, database management systems, and software development kits (SDKs) for various programming languages.
• Software as a Service (SaaS). SaaS providers offer application-level services tailored to a wide variety of business needs, such as customer relationship management (CRM), marketing automation, or business analytics.

What is AWS?

Amazon Web Services (AWS) is a subsidiary of Amazon providing on-demand cloud computing platforms and APIs to individuals, companies, and governments, on a metered pay-as-you-go basis.

Let’s talk about some aws case study:-

1- Siemens on AWS

A global leader in electrification, automation, and digitization, Siemens AG has driven innovation across industries for nearly 175 years. Siemens uses an array of AWS services to carry on that tradition of transformation — bringing IIOT to railways and factories, developing intelligent infrastructure for buildings and distributed energy systems, implementing AI into its cybersecurity platform, and more.

*Siemens Handles 60,000 Cyber Threats per Second Using AWS Machine Learning*

Siemens, the 170-year-old global technology leader, must keep a close eye on the ever-evolving landscape of cybercrime. The charter of the Siemens Cyber Defense Center (CDC) is to protect Siemens and its customers from viruses, malware, intellectual property theft, and other forms of cybercrime. It’s no small job: Worldwide, an average of 200,000 new malware samples were collected daily in 2017, a 300 percent increase over the previous year.

“On AWS, our AI-driven cybersecurity platform easily exceeds the strongest published benchmarks in the world.”

-Jan Pospisil, Senior Data Scientist, Siemens Cyber Defense Center

Siemens Uses AWS to Reduce Power Plant Alerts by 90%

It’s never been easier for power plants to monitor their equipment and operations, but the ease of deploying thousands of sensors results in a challenging volume of sensor data. That’s a challenge Siemens, the 170-year-old global technology leader, set out to answer. The solution Siemens Gas and Power built on AWS has decreased the volume of alerts for its power plant customers by 90 percent.

“A modern power plant control system receives about 5,000 alerts about component failures or out-of-tolerance process conditions a day, but monitoring teams can analyze only 500 a day,” says Stefan Lichtenberger, a program manager at Siemens Gas and Power. “Because some alerts are less important, while some warn of possible breakdowns or regulatory actions, these teams need help reducing and prioritizing alerts.”

Projects to reduce the volume of alerts can require two full-time employees for six months, and — because the volume of alerts inevitably rises again — must be repeated every two to three years.

“With the serverless AWS platform, we decreased customer control system alerts 90 percent and reduced infrastructure costs 85 percent.”

-Stefan Lichtenberger, Program Manager, Siemens Gas and Power

Siemens Smart Infrastructure Breaks Building Data Out of Silos on AWS

Siemens Smart Infrastructure is a Siemens business that works with partners and customers to intelligently connect energy systems, buildings, and industry. The company provides physical products and systems, cloud-based digital offerings, and value-added services.

“One of the biggest benefits of running on AWS is the ability to democratize data so that anyone with a good idea can build new customer value, regardless of their level of technical knowledge.”

Vice President of Trends and Industry Affairs, Siemens Smart Infrastructure

2-Slack On AWS

Slack provides a messaging platform that integrates with and unifies a wide range of communications services such as Twitter, Dropbox, Google Docs, Jira, GitHub, MailChimp, Trello, and Stripe. The San Francisco–based company, which launched its eponymous app in February 2014, was started by a small group of Silicon Valley entrepreneurs that include Flickr founder Stewart Butterfield. Privately-held Slack is on Fortune Magazine’s “Unicorn List” of startup firms worth $1 billion or more, with a $2.8 billion valuation supported by a five percent weekly user growth rate and major brand-name customers including Adobe, Samsung, Intuit, NASA, Dow Jones, eBay, and Expedia.

The Challenge

In the age of the unicorn startups, Slack has drawn attention for its meteoric rise and potential for disrupting traditional business communications tools, particularly email. By June 2015 — less than 18 months after its launch — the company already had more than 1.1 million daily users, 300,000 paid seats, and more than 30 million messages flowing through Slack each week via integrations with other services.

Slack’s founders had already learned hard lessons from previous failed ventures. One of those was the importance of picking the right IT infrastructure to run the business. If Slack was to succeed in a fiercely competitive business-software marketplace, its founders knew they would need a lean staff, low costs, and above all an IT environment capable of supporting speed, agility, and innovation. Going to the cloud was the logical choice.

“The realities of physical space, hardware acquisition, replacement parts, running a server facility with all its costs — all the physical manifestations that can lead to breakages — made a traditional IT environment impractical for an Internet startup,” says Richard Crowley, Slack’s director of operations. “Plus we would have needed an extra layer of expertise just to run the infrastructure. We could have operated with that kind of IT infrastructure, but the cost and complexity would have made it much harder to launch the business.”

Why Amazon Web Services

Crowley says Slack turned to Amazon Web Services out of experience and because it was the best choice for the company going forward. Tiny Speck — the original company name for what became Slack Technologies — used AWS in 2009 when it was the only viable offering for public cloud services.

“Given their expertise and pains running a more traditional environment when Flickr was developed, Slack’s founders realized it was a no brainer to use AWS,” says Crowley. “During the development of Slack, the feeling was that AWS was good to us and would continually improve with more and better features. There was no need to leave.”

Slack has a relatively simple IT architecture that is based on a broad range of AWS services, including i2.xlarge Amazon Elastic Compute Cloud (Amazon EC2) instances for basic compute tasks; Amazon Simple Storage Service (Amazon S3) for users’ file uploads and static assets; and Elastic Load Balancing to balance workloads across Amazon EC2 instances. Slack uses Amazon Elastic Block Store (Amazon EBS) for nightly backups of MySQL instances running on Amazon EC2 i2s instances; the Amazon EBS volumes are attached to the instances and used as temporary storage before being sent to Amazon S3. Slack replaced hundreds of terabytes of Amazon EBS gp2 volumes with lower-cost Amazon EBS sc1 volumes for database backups. Since the switch, the company continues to grow the data on its user base.

For security, Slack uses Amazon Virtual Private Cloud (Amazon VPC) to control security groups and firewall rules and AWS Identity and Access Management (IAM) to control user credentials and roles. The company uses Amazon CloudTrail for monitoring logs related to Amazon EC2 instances, and Amazon Route 53 for DNS management.

Along with the AWS services, Slack is using the Redis data structure server, the Apache Solr search tool, the Squid caching proxy, and a MySQL database.

Benefits of AWS

• Reviews user metrics daily
• Reacts to usage rates in a matter of seconds by provisioning additional capacity
• Easily practices disaster-recovery scenarios

“With traditional IT, it would take weeks or months to contend with hardware lead times to add more capacity. Using AWS, we can look at user metrics weekly or daily and react with new capacity in 30 seconds.”
