Amazon Web Services (AWS) stands as a top cloud platform that businesses trust for their daily work. It gives computing power, places to store databases, ways to share files, and tools to grow operations smoothly. In Chennai, good training programs help people learn AWS well and find strong jobs in cloud fields like setup, running systems, and planning.
How AWS Started and Why It Matters Today
AWS began from Amazon’s own need to handle IT tools better inside the company. In 2006, they opened it up for others to use through simple web ways like HTTP or REST calls. From that start, it turned into a full set of services that any business can use, no matter the size. Today, AWS runs without stops, saves money by charging only for what you use, and handles big loads like those from Netflix or big banks.
What makes AWS special is how it lets you grow fast. If your website gets more visitors, services add power right away. Safety comes built-in with rules on who can see data. Free starter accounts let new learners try things without paying. Moving old computers to AWS also has easy steps, so companies switch without big trouble. Learning this helps workers build apps quicker and spend less on hardware.
Key Services You Will Use: EC2 Explained
EC2, or Elastic Compute Cloud, acts like renting a computer over the internet. You pick the size—small ones like t2.micro cost nothing at first and suit tests. Bigger ones like m5.large run heavy jobs. Choose Windows, Linux types such as Ubuntu, or Amazon’s own setup. It runs in safe spots spread across places, so if one area has issues, others keep going.
With EC2, you control everything: add storage, set networks, or run software. Make it grow auto when busy—add more machines as traffic rises. Spot prices let you bid low for extra save, up to 90% off normal. Use it for websites, data checks, or games. In training, you learn to launch one, connect safe, and stop it clean to avoid bills.
Real work example: A shop site uses EC2 to handle orders. On sale day, it adds servers fast, then shrinks back. This keeps customers happy without waste.
S3 Storage: Safe and Simple File Keeping
S3 means Simple Storage Service. It holds any files—pictures, videos, backups—in buckets you name. Data stays safe with eleven 9s of protection, meaning almost no loss ever. Get files from anywhere quick, good for apps worldwide. Set rules: keep new files in fast storage, move old to cheap Glacier after time.
S3 grows endless, no worry on space. Share links safe or block some users. Works with EC2—save photos there straight. Costs low, pay per use. In class, practice upload big data, set access, and pull for apps. Common use: Back up company files or store user uploads.
Pair S3 with CloudFront for fast send to users far away. This cuts load times, helps sites rank better in searches.
More Important AWS Tools for Real Jobs
RDS runs databases easy—no setup hassle. Pick MySQL, Postgres, or others; it backs up auto, adds read copies for speed. Scale up power or storage with clicks. Good for apps needing SQL data.
Lambda does jobs without full servers. Write code in Java, Python; it runs on events like new file in S3. Pay only for run time, save big. Build backends or fix data auto.
VPC builds private nets in cloud, like office LAN. Set subnets, gates, safe groups to block bad traffic. CloudWatch watches all—CPU use, logs, alarms if trouble. Auto Scaling adds EC2 when needed.
These mix for full setups: EC2 runs app, S3 holds files, RDS keeps user info, Lambda checks changes.
