Everything you need to know about Amazon Web Services and how PrecisionTech deploys and manages AWS for businesses in Florida.
1
What is Amazon Web Services (AWS)?
Amazon Web Services (AWS) is the world's most comprehensive and broadly adopted cloud platform, operated by Amazon.com Inc. AWS offers over 200 fully featured cloud services — including compute (EC2), object storage (S3), managed databases (RDS, DynamoDB, Aurora), networking (VPC, Route 53, CloudFront), machine learning (SageMaker, Rekognition, Bedrock), serverless computing (Lambda), containers (ECS, EKS), DevOps tools (CodePipeline, CodeBuild), and security services (IAM, Shield, GuardDuty) — all delivered from 34 geographic regions and 108 Availability Zones worldwide, including two AWS Regions in India (Mumbai and Hyderabad).

What is the difference between AWS On-Demand, Reserved Instances, and Savings Plans?
AWS On-Demand pricing means you pay per second (or per hour) for compute with no commitment — highest flexibility, highest cost. Reserved Instances (RIs) are 1-year or 3-year commitments to specific instance types that deliver up to 72% savings over On-Demand — best for steady-state workloads. Savings Plans are more flexible — you commit to a specific dollar amount of hourly compute spend (e.g., $10/hour) rather than a specific instance type, and AWS applies discounts automatically to any EC2, Fargate, or Lambda usage — up to 66% savings. PrecisionTech analyzes your workload patterns and recommends the optimal mix of On-Demand, Reserved Instances, and Savings Plans to minimize your AWS bill without sacrificing flexibility.
4
How does cloud migration to AWS work? How long does it take?
PrecisionTech follows AWS's 6R migration strategy: (1) Rehost — lift-and-shift existing servers to AWS EC2 with minimal changes; fastest approach, typically 2-8 weeks for SMBs. (2) Replatform — move to managed AWS services (e.g., migrate MySQL to Amazon RDS) for lower operational overhead. (3) Refactor — re-architect applications to use cloud-native services (Lambda, ECS, DynamoDB) for maximum scalability and cost efficiency. (4) Repurchase — replace legacy software with SaaS equivalents available on AWS Marketplace. (5) Retire — decommission unused workloads identified during discovery. (6) Retain — keep specific systems on-premises if not yet ready for cloud. Migration timelines range from 2 weeks (simple lift-and-shift) to 6 months (large enterprise re-architecture). PrecisionTech provides a free Migration Readiness Assessment to estimate your timeline.
5
What are the two AWS data centre regions in India and why do they matter?
AWS has two regions in India: ap-south-1 (Mumbai, launched 2016) with 3 Availability Zones, and ap-south-2 (Hyderabad, launched 2022) with 3 Availability Zones. Using an India region is critical for: (1) Data residency compliance — Indian regulations (DPDP Act 2023, RBI data localisation, SEBI, IRDAI mandates) require certain data to remain within India. (2) Latency — India-region endpoints deliver 10-30ms round-trip times to Indian users vs 150-250ms from US or Europe regions. (3) AWS Local Zones in Mumbai extend latency-sensitive services even closer to users. PrecisionTech designs all Indian client architectures to leverage ap-south-1 and ap-south-2 with cross-region replication for DR.
6
How does AWS pricing work? Is it expensive?
AWS uses a pay-as-you-go model — you pay only for what you use, billed per second for compute (EC2, Lambda) and per GB for storage (S3, EBS). There are no upfront costs for On-Demand usage. AWS pricing is typically 20-40% lower than running equivalent on-premises infrastructure when you factor in hardware refresh costs, data centre overhead, power, cooling, and IT staff. With Reserved Instances or Savings Plans, costs drop further by up to 72%. PrecisionTech provides monthly cost reports, anomaly detection, and continuous optimization recommendations so your AWS spend never surprises you.
7
What is AWS Well-Architected Framework and why does it matter?
The AWS Well-Architected Framework is a set of best practices across 6 pillars — Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability — that guides architects in building robust, secure, and efficient cloud workloads. As an AWS Partner, PrecisionTech conducts official Well-Architected Reviews (WARs) on your existing AWS environment, producing a prioritized list of High Risk Issues (HRIs) and Medium Risk Issues (MRIs) with remediation plans. AWS Partners can apply for AWS-funded credits to remediate HRIs identified during WARs. This is a free service PrecisionTech offers to clients with active AWS accounts.
8
How does PrecisionTech help with AWS security and compliance?
PrecisionTech implements AWS security best practices across: (1) Identity & Access Management — least-privilege IAM roles, MFA enforcement, AWS Organizations SCPs, and AWS SSO; (2) Network security — VPC design with private subnets, Security Groups, NACLs, AWS WAF, and Shield Advanced; (3) Threat detection — AWS GuardDuty (ML-based threat detection), AWS Security Hub (centralized findings), Amazon Macie (sensitive data discovery in S3); (4) Compliance automation — AWS Config rules for continuous compliance monitoring against CIS Benchmarks, NIST, ISO 27001, HIPAA, PCI-DSS, and RBI guidelines; (5) Audit and forensics — CloudTrail for API audit logs, VPC Flow Logs, and S3 access logging; (6) Data encryption — KMS customer-managed keys for all data at rest, TLS 1.3 for data in transit.
9
What is Amazon EC2 and which instance types are best for Indian businesses?
Amazon EC2 (Elastic Compute Cloud) provides resizable virtual servers (instances) in the cloud. Key instance families for Indian businesses: General Purpose (t3/t4g, m6i/m7i) — web servers, app servers, small databases; Compute Optimized (c6i/c7i) — high-performance computing, batch processing, video encoding; Memory Optimized (r6i/r7i, x2idn) — in-memory databases, SAP HANA, large caches (ElastiCache); Storage Optimized (i4i, d3) — high I/O databases, data warehousing; GPU Instances (p3, p4, g5) — machine learning training, video rendering. AWS Graviton3-based instances (c7g, m7g, r7g) offer the best price-performance ratio — up to 40% better performance at 20% lower cost than equivalent x86 instances. PrecisionTech helps you select and right-size instances for your specific workload.
10
What is Amazon S3 and how is it used for business data?
Amazon S3 (Simple Storage Service) is AWS's object storage service offering 99.999999999% (11 nines) durability. Key business use cases: (1) Static website and CDN origin for CloudFront; (2) Data lake — store raw business data for analytics with Athena, Glue, and Redshift Spectrum; (3) Application backup target — Acronis, Veeam, and native AWS Backup all support S3; (4) Media storage and delivery — images, videos, documents; (5) Log archiving — CloudTrail, ALB, and CloudFront logs; (6) Machine learning training datasets. S3 storage classes (Standard, Intelligent-Tiering, Standard-IA, Glacier Instant Retrieval, Glacier Deep Archive) let you automatically tier cold data to as low as $0.00099/GB/month, dramatically reducing storage costs for archival data.
11
What is Amazon RDS and how does it differ from running a database on EC2?
Amazon RDS (Relational Database Service) is a fully managed database service supporting MySQL, PostgreSQL, MariaDB, Oracle, SQL Server, and Amazon Aurora. Compared to self-managed databases on EC2: RDS handles automated backups (up to 35-day retention with point-in-time recovery), software patching, Multi-AZ failover (sub-60-second automatic failover to a standby replica), Read Replicas for horizontal read scaling, storage auto-scaling, and Performance Insights for query-level monitoring. Amazon Aurora is AWS's high-performance managed database compatible with MySQL and PostgreSQL — it delivers up to 5x MySQL performance and 3x PostgreSQL performance at 1/10th the cost of commercial databases like Oracle. PrecisionTech migrates on-premises MySQL, MSSQL, and Oracle databases to RDS/Aurora using AWS DMS (Database Migration Service) with minimal downtime.
12
What is AWS Lambda and serverless computing?
AWS Lambda is a serverless compute service that runs your code in response to events (HTTP requests via API Gateway, S3 uploads, DynamoDB streams, scheduled cron, etc.) without provisioning or managing servers. You pay only for the compute time consumed — measured in milliseconds — with a free tier of 1 million requests and 400,000 GB-seconds per month. Lambda is ideal for: API backends, ETL pipelines, image processing, IoT data processing, and chatbots. Lambda supports Node.js, Python, Java, Go, Ruby, .NET, and custom runtimes. PrecisionTech architects serverless solutions using Lambda + API Gateway + DynamoDB + S3 that can scale from zero to millions of requests per day with zero infrastructure management.
13
How does AWS help with disaster recovery (DR)?
AWS enables multiple DR strategies depending on your RTO/RPO requirements: (1) Backup & Restore — cheapest, RPO hours, RTO hours; data backed up to S3/Glacier, restored on EC2 when needed. (2) Pilot Light — critical systems (DB) always running in AWS, app servers pre-configured but stopped; RPO minutes, RTO 10-30 min. (3) Warm Standby — scaled-down but fully functional copy of production running in AWS; RPO seconds, RTO 5-15 min. (4) Multi-Site Active-Active — full production capacity in two or more regions; RPO near-zero, RTO near-zero. PrecisionTech designs and tests your DR architecture, performs quarterly DR drills, and maintains runbooks so your team can execute recovery confidently under pressure.
14
What is AWS CloudFront and how does it improve website performance in India?
Amazon CloudFront is AWS's global Content Delivery Network (CDN) with 600+ Points of Presence (PoPs) worldwide, including multiple edge locations in India (Mumbai, Chennai, Hyderabad, Delhi, Kolkata, Bengaluru). CloudFront caches static content (images, CSS, JS, videos) at the edge nearest to the user — reducing latency from 150-200ms (origin server round-trip) to 5-20ms (edge cache hit). Beyond static content, CloudFront supports: Lambda@Edge for dynamic content personalization at the edge, AWS WAF integration for DDoS protection, real-time streaming with HLS/DASH, and secure delivery with field-level encryption. For Indian e-commerce, media, and SaaS businesses, CloudFront typically improves page load times by 40-70%, directly impacting Google Core Web Vitals scores and SEO rankings.

16
What is AWS Cost Explorer and how does PrecisionTech use it to save money?
AWS Cost Explorer is a native AWS tool that visualizes your spend patterns across services, regions, linked accounts, and tags. PrecisionTech uses Cost Explorer along with AWS Trusted Advisor, Compute Optimizer, and third-party tools (CloudHealth, Apptio Cloudability) to: identify idle EC2 instances and unattached EBS volumes for immediate termination; recommend Savings Plans and Reserved Instance purchases based on 90-day usage patterns; detect anomalous cost spikes in real time with Cost Anomaly Detection; implement resource tagging strategies for accurate cost allocation by department/project; and manage multi-account billing consolidation via AWS Organizations. Our cost optimization reviews typically reduce client AWS bills by 20-40% within 60 days.
17
What compliance certifications does AWS hold, and how does this help Indian businesses?
AWS maintains over 143 security certifications and compliance attestations including: ISO 27001, ISO 27017, ISO 27018, ISO 9001, SOC 1/2/3, PCI DSS Level 1, HIPAA, FedRAMP, GDPR, CSA STAR, and India-specific certifications including MEITY empanelment (for Government of India workloads) and RBI-compliant architecture frameworks. For Indian businesses, building on AWS means inheriting the underlying infrastructure compliance — reducing your own compliance scope and audit burden. PrecisionTech maps AWS compliance artifacts to your specific regulatory requirements (RBI, SEBI, IRDAI, DPDP Act 2023, HIPAA for Indian healthcare) and implements the application-level controls needed to achieve full regulatory compliance.
18
How does AWS AI/ML help Indian businesses, and what services are available?
AWS offers the most comprehensive AI/ML service portfolio of any cloud provider: Amazon SageMaker (end-to-end ML platform for building, training, and deploying models), Amazon Bedrock (managed foundation models — Claude, Llama, Titan, Stable Diffusion — for generative AI applications), Amazon Rekognition (image and video analysis — face detection, OCR, object identification), Amazon Comprehend (NLP — sentiment analysis, entity recognition, language detection for Indian languages), Amazon Translate (neural machine translation supporting Hindi, Tamil, Telugu, Marathi, and 10+ Indian languages), Amazon Textract (intelligent document processing — extract data from forms, invoices, ID documents), Amazon Forecast (time-series forecasting for demand planning, inventory optimization), and Amazon Polly (text-to-speech in Indian languages). PrecisionTech architects and deploys production AI/ML solutions on AWS for Indian enterprises across manufacturing, BFSI, healthcare, and retail.

What AWS support plan should I choose?
AWS offers 4 native support tiers: Basic (free — documentation and community forums only), Developer ($29/month or 3% of AWS bill — business-hours email support, 12-24hr response), Business ($100/month or 10% of bill — 24×7 phone/chat/email, 1-hr response for production system down), Enterprise ($15,000/month — Technical Account Manager, 15-min response for critical issues, Trusted Advisor full checks). PrecisionTech supplements AWS native support with our own 24×7 India-based managed services SLA — providing faster-than-Business-tier response in IST business hours, Hindi/English support, and dedicated account management. Most Indian SMBs get the best value by pairing AWS Developer support with PrecisionTech's managed services rather than paying for AWS Business or Enterprise tiers.
21
How does AWS pricing work in Indian Rupees (INR)? Can I get an INR invoice with GST?
AWS bills in US Dollars (USD) by default. However, when you procure AWS through an Authorized AWS Partner like PrecisionTech, we consolidate your AWS usage billing and issue INR invoices with 18% GST — significantly simplifying accounts payable and eliminating foreign currency exposure. AWS India pricing typically follows a USD-to-INR conversion published monthly by AWS. For compute (EC2 in Mumbai ap-south-1), pricing runs from approximately ₹0.37/hour for a t3.micro to ₹80+/hour for a high-memory r7i.24xlarge. PrecisionTech provides month-on-month INR cost reports, GST invoices, and proactive cost forecasting so your finance team always has predictable cloud spend. Contact us to get a customized INR cost estimate using the AWS Pricing Calculator for your specific workload.
22
How does the Digital Personal Data Protection Act (DPDP Act 2023) affect Indian businesses using AWS?
The Digital Personal Data Protection (DPDP) Act 2023 is India's landmark data privacy law that governs the collection, storage, and processing of personal data of Indian citizens. Key implications for AWS users: (1) Data Localisation — while DPDP Act does not mandate data localisation for all data (unlike earlier drafts), certain sectors (BFSI, healthcare, government) have existing RBI, SEBI, and MeitY localisation requirements that require India-region AWS storage. Using ap-south-1 (Mumbai) or ap-south-2 (Hyderabad) satisfies this requirement. (2) Data Processing Agreements — DPDP requires formal data processing agreements with cloud providers; AWS offers a Data Processing Addendum (DPA) that PrecisionTech helps you execute. (3) Breach Notification — AWS CloudTrail, GuardDuty, and Security Hub provide the audit logs and alerting needed for the mandatory 72-hour breach notification requirement. (4) Data Erasure — S3 lifecycle policies, RDS deletion protection, and DynamoDB TTL support right-to-erasure compliance. PrecisionTech provides a complete DPDP Act compliance assessment for your AWS environment.
23
What is the AWS Pricing Calculator and how can I estimate my AWS costs before migrating?
The AWS Pricing Calculator (calculator.aws) is a free tool that lets you model your expected AWS costs before committing. You can configure EC2 instance types, storage (S3, EBS, EFS), databases (RDS, DynamoDB), data transfer, and add-on services to get a monthly cost estimate in USD or INR. Key inputs: (1) Compute — instance type (e.g., m7i.large), operating system (Linux/Windows), pricing model (On-Demand, Reserved, Savings Plans), and hours/month; (2) Storage — S3 storage class, total GB, request rates, data transfer out; (3) Database — RDS engine, instance class, Multi-AZ, storage, backup retention, data transfer. As part of our free Cloud Readiness Assessment, PrecisionTech builds a detailed Pricing Calculator model for your specific workload, including Reserved Instance recommendations, to produce an accurate TCO comparison between your current on-premises costs and your estimated AWS spend. This helps you make a data-driven migration decision.
24
What are AWS Graviton instances and should Indian businesses use them?
AWS Graviton processors are Amazon's custom ARM-based processors (Graviton2, Graviton3, Graviton4) designed specifically for AWS cloud workloads. Graviton3-based instances (c7g, m7g, r7g, t4g) offer up to 40% better price-performance compared to equivalent Intel x86 (c6i, m6i, r6i) instances for the same workload — because ARM architecture delivers the same compute at lower clock speeds with significantly better power efficiency. For Indian businesses, Graviton instances are well-suited for: Java Spring Boot applications (ARM JVM is fully optimized), Python/Django/Flask APIs, Node.js backends, MySQL/PostgreSQL on RDS (Graviton2 RDS supports all major engines), PHP/Laravel, and containerized microservices on ECS/EKS. Graviton instances are NOT suitable for: Windows workloads (Windows AMIs are not available on Graviton), legacy x86-compiled binaries without recompilation, or specific commercial software without ARM support. PrecisionTech evaluates Graviton compatibility for each workload during the Cloud Readiness Assessment and migrates eligible workloads to reduce compute costs by 20-40%.
