Crafting Robust Applications Across AWS, On-Premises, and Data Centers: A Comprehensive Technical Guide

This technical blog explores how AWS services, tools, and strategies can address modern challenges in cloud strategy, security posture, disaster recovery, and more.
AWS Outposts, VMware Cloud on AWS, and AWS Local Zones can extend AWS services to on-premises environments for low-latency applications and deploy applications closer to end-users.
Terraform or Crossplane can be used for multi-cloud IaC management. AWS Transit Gateway is ideal for secure and scalable connectivity between clouds.
AWS Migration Hub, AWS DMS and AWS Snow Family are tools that help minimize downtime and cost efficiency during migration. Strategies like Route 53 Weighted DNS, RDS Multi-AZ Deployments and blue-green deployments also reduce the impact on production systems.
AWS Security Hub, Amazon GuardDuty, and AWS Firewall Manager ensure security and compliance across AWS and on-premises environments. Self-Remediation with AWS Lambda triggered by CloudWatch Events can help fix non-compliant resources in real-time.
Amazon ECS and EKS, AWS Lambda, and ALB are some of the AWS services used for scalability and improving high availability. Amazon RDS Multi-AZ and Amazon Route 53 ensure failover capabilities and DNS failover and traffic routing based on health checks.
AWS Cost Explorer, AWS Trusted Advisor, and Savings Plans & Reserved Instances are some of the tools that help organizations manage cloud cost effectively. Spotify and Slack are case-studies of organizations that utilize cost monitoring tools to save costs.
AWS Backup, AWS DRS, Amazon S3 Versioning and Replication, and Pilot Light or Warm Standby Architectures are some AWS solutions for disaster recovery and backup. Bank of America and Airbnb are examples of organizations that deploy cross-region disaster recovery setups with high goals.
Amazon CloudWatch, AWS X-Ray, and Amazon OpenSearch Service are some tools provided by AWS to help with observability and monitoring. LinkedIn and Monzo Bank are examples of organizations that utilize custom monitoring pipelines with high-frequency metrics collection.
AWS CodePipeline, AWS CodeDeploy, and AWS CodeBuild can be used for deployment automation, along with IaC Tools like CloudFormation or Terraform. Tesla and Pinterest utilize advanced CI/CD pipelines with Helm charts for application deployment automation.

Concept of Infrastructure Monitoring

Infrastructure monitoring involves continuous collection, analysis, and visualization of performance metrics from an organization's IT infrastructure.
Infrastructure monitoring is important for ensuring system reliability, proactive issue resolution, optimizing resource usage, scalability support, compliance facilitation, and enhancing user experience.
Key metrics that need to be monitored in infrastructure monitoring include server metrics, network metrics, application metrics, and security metrics.
The components of infrastructure monitoring include data collection, data aggregation, visualization, alerting, and automation.
Prometheus, Nagios, Grafana, Datadog, ELK Stack, AWS CloudWatch, and Zabbix are some of the tools used for infrastructure monitoring.
The steps involved in setting up infrastructure monitoring include defining goals, choosing tools, deploying agents, setting thresholds, creating dashboards, implementing alerting, and testing the setup.
Best practices for infrastructure monitoring include monitoring holistically, setting realistic alerts, automating where possible, regularly reviewing metrics, and integrating security.
New Relic is a powerful Application Performance Monitoring (APM) tool that provides detailed insights into the performance of your applications and infrastructure.
The key features monitored with New Relic include application metrics, database performance, server metrics, transaction tracing, and external services.
By leveraging tools like New Relic, organizations can gain real-time insights, resolve issues quickly, and improve user experience with a more comprehensive solution.

Ephemeral Environments: A Quick Overview

Ephemeral environments are becoming the industry standard for testing and previewing features before they hit staging.
Ephemeral environments are generally provisioned upon every pull request, enabling every feature testing in isolation prior to a merge.
Teams that use ephemeral environments to test features tend to ship faster, test more often, review more thoroughly, and trust their deployments more.
Ephemeral environments are at the sweet spot between cost efficiency and production parity.
Ephemeral environments are entirely isolated from the rest of the infrastructure, full-stack, and near-production copies of the application.
Ephemeral environments are GitOps-enabled, short-lived, and automate the repetitive tasks required.
Ephemeral environment automate the testing workflow, enabling more developers to work more efficiently and review asynchronously.
Ephemeral environments have a positive ripple effect on DORA and DevEx metrics, which help teams benchmark their performance and improve the quality of their processes.
Ephemeral environments have a massive ROI relative to their cost and effort and benefit engineering processes in nearly every possible way.
Ephemeral environments are cost-effective, promote collaboration, improve developer QoL, and enable teams to ship faster.

Surfshark’s shortest subscription is expensive. At $15.45 monthly, you’d pay more than $185 each year.
Surfshark offers much more affordable prices when you pay for one or two years in advance.
VPN Unlimited has a surprise in its price structure. You can subscribe monthly for $10, annually for $60, or pay a one-time fee of $200 to get a lifetime subscription and keep using the VPN forever.
Surfshark was the fastest VPN with download speed reaching 728Mbps. VPN Unlimited’s best speed was a fast 595Mbps for a U.S. server. Overseas connections were significantly slower.
Both VPNs offer advanced features like kill switches to stop unprotected internet use, split-tunneling to exclude select apps from the VPN for optimal speed, and more.
Surfshark offers quick, friendly live chat that’s available all day, every day. VPN Unlimited offers 24/7 email support.
Both VPNs have privacy policies that state none of your personal data is shared or sold to third-party advertisers.
