What is AWS?

AWS (Amazon Web Services) ek cloud computing platform hai jo Amazon ne banaya hai. Yeh platform businesses aur developers ko apne applications, websites, aur data ko internet par securely store aur manage karne ka option deta hai. AWS ke paas 100+ cloud services hain jo har tarah ke projects aur businesses ki needs ko cover karti hain, jaise computing power, storage, databases, machine learning, aur security.

AWS ka sabse bada fayda yeh hai ki aapko physical servers maintain karne ki zarurat nahi hoti. Aap pay-as-you-go model par sirf utna hi paise dete hain jitna aap use karte hain.

AWS ke Kuch Popular Services

1. EC2 – Virtual servers (compute power)

2. S3 – Storage for data

3. RDS – Managed database services

4. Lambda – Serverless computing

5. CloudFront – Content delivery network

Traditional Cloud vs AWS

Traditional Cloud

Traditional cloud platforms mein, aapko ek specific location par dedicated servers ya data centers ki zarurat hoti hai. Inme aapko apni infrastructure ko setup aur maintain karna padta hai. Yeh kaafi costly aur time-consuming ho sakta hai.

AWS Cloud

AWS ek on-demand platform hai, jisme aapko sirf required resources milte hain. AWS par aap easily compute power, storage aur databases ko scale up ya scale down kar sakte ho, bina kisi additional setup ke. AWS cloud ki flexibility aur scalability isse traditional cloud services se kaafi aage rakhti hai

Cloud Computing Service Models par focus karte hain. Yeh topic beginners ke liye important hai, kyunki isse unhe samajh aata hai ki AWS ke different service models ka use kaise kar sakte hain.

Cloud Computing Service Models

Cloud computing mein 3 main service models hote hain:

1. Infrastructure as a Service (IaaS)

IaaS model mein, cloud service provider (AWS) aapko basic infrastructure resources provide karta hai, jaise virtual machines (compute), storage, aur networking. Aap in resources ka use karte ho bina physical hardware ko maintain kiye.

Example:

• Amazon EC2 (virtual servers)

• Amazon S3 (cloud storage)

Advantages:

• Aapko physical hardware manage karne ki zarurat nahi hoti.

• Scalability aur flexibility milti hai.

• Pay-as-you-go pricing.

2. Platform as a Service (PaaS)

PaaS model mein, cloud provider aapko complete platform provide karta hai, jisme operating system, middleware, database, aur runtime environment included hoti hai. Aapko sirf apne application ko deploy karna hota hai.

Example:

• AWS Elastic Beanstalk (Platform for deploying web apps)

• Google App Engine

Advantages:

• Developers ko infrastructure setup ki tension nahi hoti.

• Focus apne application development par hota hai, na ki server configuration par.

3. Software as a Service (SaaS)

SaaS model mein, cloud provider complete software application ko internet ke through provide karta hai. Aapko software ko install aur maintain karne ki zarurat nahi hoti, bas internet se access karte ho.

Example:

• Gmail

• Google Drive

Advantages:

• No need to manage hardware or software.

• Easily scalable aur updated versions available hote hain.

Cloud Deployment Models par focus karte hain. Yeh topic cloud environments ke types ko explain karega, jisme Public Cloud, Private Cloud, aur Hybrid Cloud include hain. Yeh beginners ke liye important hai taaki wo samajh sakein ki kaunsa model unki needs ke liye best hai.

Cloud Deployment Models

Cloud deployment models ke teeno types ka apna use case aur advantages hain. Chaliye inhe detail mein samajhte hain:

1. Public Cloud

Public Cloud model mein, cloud services aur resources ko third-party cloud providers (jaise AWS, Google Cloud, Microsoft Azure) publically access karne ke liye available karte hain. Ismein aapko apne data center ki zarurat nahi hoti, aur resources on-demand available hote hain.

Example:

• Amazon Web Services (AWS)

• Google Cloud Platform (GCP)

• Microsoft Azure

Advantages:

• Cost-effective: Pay-as-you-go model, jisme aapko sirf use kiye gaye resources ka hi payment karna padta hai.

• Scalable: Resources ko easily scale kiya ja sakta hai.

• Managed by provider: Server maintenance aur hardware management ka tension nahi hota.

2. Private Cloud

Private Cloud model mein, cloud resources ek specific organization ke liye dedicated hote hain. Yeh ek on-premise setup ho sakta hai ya phir third-party data center mein, lekin isme access sirf organization ke internal users ke liye hota hai.

Example:

• VMware Private Cloud

• OpenStack

Advantages:

• High Security: Data aur applications ke liye customized security policies create ki ja sakti hain.

• Full Control: Organization ko apne infrastructure par full control milta hai.

• Compliance: Sensitive data ke liye zyada control aur compliance manage kiya ja sakta hai.

3. Hybrid Cloud

Hybrid Cloud model mein, Public aur Private Cloud dono ka combination hota hai. Isme organization ko flexibility milti hai ki wo sensitive data ko private cloud mein rakh sake, aur non-sensitive tasks ko public cloud mein execute kar sake.

Example:

• AWS Hybrid Cloud Services (EC2 + Private Cloud)

• Azure Hybrid Cloud

Advantages:

• Best of Both Worlds: Public aur private cloud ki flexibility milti hai.

• Cost Efficiency: Non-sensitive workloads ko public cloud mein shift kar ke cost save kiya ja sakta hai.

• Scalability aur Security: Sensitive data ko private cloud mein secure rakha ja sakta hai, aur public cloud se scaling kiya ja sakta hai.

---

Summary:

• Public Cloud: Shared resources, low cost, easy to scale.

• Private Cloud: Dedicated resources, more control, high security.

• Hybrid Cloud: Combination of public and private clouds for better flexibility.

AWS Pricing and How AWS Charges par focus karenge. Yeh topic cloud users ke liye kaafi important hai, kyunki AWS ka pricing model thoda different hota hai aur samajhna zaroori hai taaki aap apne resources ka cost-effective tareeke se use kar sakein.

How AWS Charges & AWS Pricing

AWS apne customers se pay-as-you-go model ke through charge karta hai. Matlab, aapko sirf un resources ka hi pay karna padta hai jo aap use karte ho. AWS ka pricing model thoda complex ho sakta hai, lekin agar aap samajh lein ki kis service ka pricing kis tarah se kaam karta hai, toh aap apni costs efficiently manage kar sakte ho.

AWS Pricing Models

AWS ka pricing model 4 main categories mein divide hota hai:

1. On-Demand Pricing
   Is pricing model mein aapko sirf us time ke liye charge kiya jata hai jab aap AWS services ko use kar rahe hote hain. Isme aapko upfront cost ya long-term commitment ki zarurat nahi hoti. Yeh model small businesses aur startups ke liye best hai.

   Example:

   • Amazon EC2 instances ko aap on-demand basis par launch kar sakte hain aur unse billing hoti hai.

2. Reserved Pricing
   Is model mein aap ek specific period ke liye resources reserve karte hain (e.g., 1 year ya 3 years). Aapko pehle se pay karna padta hai, lekin aapko significant discounts milte hain, jo long-term users ke liye faydemand hai.

   Example:

   • Amazon EC2 Reserved Instances: Aap resources ko pre-commit karte hain aur monthly fixed rates par discounts paate hain.

3. Spot Pricing
   Spot instances aapko un resources ke liye milte hain jo AWS ke paas available hote hain, lekin jo currently unused hote hain. Is model mein aapko significant discounts milte hain, lekin aapko apne workloads ko flexible rakhna padta hai, kyunki AWS in instances ko kabhi bhi terminate kar sakta hai.

   Example:

   • Amazon EC2 Spot Instances: Low-cost instances jo aapko 90% tak discounted price par milte hain, lekin termination risk hota hai.

4. Free Tier
   AWS Free Tier model mein aapko kuch specific services limited usage ke liye free milti hain. Yeh model beginners ke liye helpful hai, jo apni learning aur testing ke liye AWS services ko explore karna chahte hain.

   Example:

   • Amazon EC2: 750 hours per month free for the first 12 months.

   • Amazon S3: 5GB storage free for the first 12 months.

Factors Affecting AWS Pricing

1. Service Type
   Har service ka alag pricing hota hai. Jaise EC2 ka pricing compute power pe based hota hai, aur S3 ka pricing storage ke amount pe.

2. Region
   AWS ka pricing different regions mein vary karta hai. Agar aap AWS resources ko ek cheaper region mein deploy karte ho, toh aapki overall cost kam ho sakti hai.

3. Data Transfer
   AWS mein data transfer (especially outside AWS network) ke liye alag charges hote hain.

4. Resource Usage
   Aap kitna CPU, memory, aur storage use kar rahe ho, iske hisaab se charges hote hain.
