CloudFront is a content delivery network (CDN) created by Amazon. It uses a global distribution of servers for caching the data, providing global clients with quick and unrestricted access to content.
CloudFront can also improve a company’s UI/UX functionality through content. You can also use it to direct organic traffic to your website.
CloudFront is highly secured and offers data protection at both the network and application levels. It can detect DDoS and cloud attacks along with malicious interference. AWS Shield and AWS Web Application Firewall (WAF) features also add to CloudFront’s overall security. It’s also compliant with IT security companies such as PCI, SOC 1/2/3, ISO/IEC, and HIPAA.
Hiring Guide
CloudFront’s speed of data transfer is very high. It also optimizes cache behavior along with network-layer optimizations. This minimizes latency and improves throughput.
You can use CloudFront’s API for distributing text content, applications, and videos. Once you define CloudFront’s distribution and origins (i.e., the content that has to be transferred and the server in which the content is located), the network transfers the content through different locations and caches to ensure agility, low latency, and precision.
CloudFront in today’s industry
CloudFront is an important part of today’s content distribution strategy for companies of all types. It allows them to deliver content across the world with utmost precision and consistency. It also assists in software distribution and API acceleration. Many businesses such as Airbnb, Pinterest, Amazon, Instacart, Netflix, and Dropbox use CloudFront to distribute their data.
CloudFront is highly cost-effective. It charges only for the services which you actually use. Its upfront fee is also very affordable, and it doesn’t require a minimum number of traffic commits to be done every month. You can also customize your plan pricing through the CloudFront security savings bundle.
Issues companies have when hiring CloudFront engineers.
Many companies these days are implementing CloudFront for their data and content distribution. This task requires an engineer who can troubleshoot distribution issues and can handle common errors in implementation. These issues are often difficult to handle, and very few engineers actually know how to do so effectively.
Along with debugging, a CloudFront engineer also needs to focus on content distribution settings. A wrong setup will slow down your content distribution and hinder your strategy. The setup processes are sometimes complicated, and the engineer needs to ensure that the data/content is getting the attention it deserves.
The engineer may also need to work on an outage strategy, i.e., if AWS goes down. This job demands an experienced engineer who has experience with these scenarios.
How to select the perfect CloudFront engineer?
Before hiring a CloudFront engineer, you need to check their knowledge of CloudFront customization and integration. They should have experience in APIs and webhooks and should be able to integrate AWS tools into existing infrastructure.
The selected engineer should know how to perform debugging and troubleshooting on code modules. In addition, they should have expertise in network security, DDoS attacks, and DNS services.
The engineer should know programming languages such as C++, Java, and C#. They should also be well-versed with internet protocols such as HTTP and TCP.
Interview Questions
What do you understand about CloudFront regional edge cache?
CloudFront transmits the content via an international network of data centers known as edge locations. The regional edge caches are locations near particular viewer clusters, specifically placed for quick data transmission.
They are located between the original web server and the global edge locations. They improve performance by increasing the bit transfer rate and decreasing operational and scaling expenses.
Can you use CloudFront for dynamic content?
Yes, you can use CloudFront for dynamic content. You can also set up options for cache modification, query customization, and cookie information for optimizing dynamic content.
How are real-time metrics captured in CloudFront?
You can use Amazon CloudWatch for generating granular and operational metrics in CloudFront. It also displays standard and real-time logs.
The standardized logs by Amazon CloudFront also facilitate logging for distribution networks. They automatically transfer records to an S3 bucket that you can later use for reporting.
What are some of the popular use cases for CloudFront?
Quick Content Distribution: You can share different types of content worldwide through CloudFront’s caching mechanism. It can handle thousands of requests per second and is highly scalable. You can also distribute dynamic and customized content quickly through CloudFront.
Streaming: CloudFront can also be used for streaming videos and for playing videos on demand.
Software distribution: CloudFront can be used for delivering software solutions across the world. It can also improve API calls.
Private content: You can set up security parameters for ensuring that only a certain population segment can view your content. You can also whitelist IPs with special permissions through geotargeting.
What are CachedMethods?
This is an array that determines for which HTTP methods CloudFront can use cache memory. It can cache responses for different functions such as GET, HEAD, PUT, OPTIONS, and DELETE.
