How to improve applications performance which is hosted in cloud ?

Improving the performance of an application hosted in Microsoft Azure involves a combination of optimizing your application code, leveraging Azure services, and following best practices for cloud-based deployments. Here are some specific steps you can take to enhance the performance of your Azure-hosted application:

Choose the Right Azure Services: Select Azure services that align with your application's needs. For example, Azure App Service, Azure Functions, Azure Kubernetes Service (AKS), and Azure Virtual Machines offer different levels of control and scalability. Choose the appropriate service based on your workload.

Scale Horizontally: Leverage Azure's scaling capabilities to handle increased traffic. Implement auto-scaling for your application to dynamically adjust resources based on demand.

Content Delivery Network (CDN): Use Azure CDN to distribute content globally, reducing latency for users by caching static assets closer to them.

Azure Front Door or Azure Traffic Manager: Utilize services like Azure Front Door or Azure Traffic Manager for load balancing and to route traffic to the nearest and healthiest endpoint, improving availability and response times.

Azure SQL Database Optimization: If you're using Azure SQL Database, optimize query performance by creating appropriate indexes, partitioning tables, and leveraging features like query performance insights.

Azure Redis Cache: Implement Azure Redis Cache to store frequently accessed data in-memory, reducing the need to query the database for every request.

Azure Application Insights: Integrate Application Insights for real-time monitoring, performance tracking, and identifying bottlenecks in your application.

Use Managed Services: Azure offers a range of managed services like Azure Cosmos DB, Azure Search, and Azure Functions that are optimized for performance and scalability.

Geo-Replication: If your application is used across different regions, use Azure's geo-replication features to replicate data and ensure low-latency access for users.

Azure Blob Storage: Store static assets, media files, and other large objects in Azure Blob Storage to offload the web server and improve load times.

Optimize Network Traffic: Use Azure ExpressRoute for dedicated private network connections between Azure and your on-premises infrastructure to minimize latency and improve data transfer rates.

Use Azure Availability Zones: Deploy resources across Azure Availability Zones for high availability and redundancy, reducing the risk of downtime due to infrastructure failures.

Azure Managed Kubernetes (AKS): If using AKS, optimize your containerized applications by configuring appropriate resource limits, managing pod scaling, and monitoring performance.

Compress Data: Enable data compression for web resources to reduce transfer times and improve page load speed.

Azure Functions Cold Starts: If using Azure Functions, implement strategies to minimize cold starts by using warm-up requests or utilizing Premium Plan features.

Azure Virtual Network: Use Azure Virtual Network to isolate your application from other resources and optimize network traffic.

Regular Performance Testing: Conduct regular performance testing and load testing to identify performance bottlenecks and validate your optimizations.

Azure Cost Management: Optimize resource utilization to avoid overprovisioning and control costs while maintaining performance.

Remember that performance optimization is an ongoing process. Continuously monitor your application's performance using Azure monitoring tools and make adjustments as needed. Each application is unique, so tailor these recommendations to your specific requirements and architecture.

What happens when you type a URL into your browser?

URL stands for Uniform Resource Locator. URL is the address of the website which you can find in the address bar of your web browser.

Example : https://www.debuggersspace.com/ 

DNS : DNS is short for Domain Name System. Like a phonebook, DNS maintains and maps the name of the website, i.e. URL, and particular IP address it links to. Every URL on the internet has a unique IP address which is of the computer which hosts the server of the website requested.

CNAME recordA Canonical Name record is a type of resource record in the Domain Name System that maps one domain name to another. This can prove convenient when running multiple services from a single IP address.

Steps for what happens when we enter a URL :

  1. Browser checks cache for DNS entry to find the corresponding IP address of website.
    It looks for following cache. If not found in one, then continues checking to the next until found.
    • Browser Cache
    • Operating Systems Cache
    • Router Cache
    • ISP Cache
  2. If not found in cache, ISP’s (Internet Service Provider) DNS server initiates a DNS query to find IP address of server that hosts the domain name.
    The requests are sent using small data packets that contain information content of request and IP address it is destined for.
  3. Browser initiates a TCP (Transfer Control Protocol) connection with the server 
  4. Browser sends an HTTP request to the web server. GET or POST request.
  5. Server on the host computer handles that request and sends back a response. It assembles a response in some format like JSON, XML and HTML.
  6. Server sends out an HTTP response along with the status of response.
  7. Browser displays HTML content
  8. Finally, Done.

What is cloud computing?

Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.

here are several examples of cloud computing applications -

1. Cloud service would be streaming platforms for audio or video, where the actual media files are stored remotely.

2. Data storage platforms like Google Drive, Dropbox, OneDrive
