I think the choice in the first single shows that Hayden is aware of this. In the EPs the narrator is always at least semi neutral. And obv PD is from the perspective of Ethel.

"Spoilers" for the verses of punish under the cut. But like... She performed it live and put these lyrics up on genius herself. Y'all have been warned.

If the verses in punish are to be taken literally, this is from the perspective of a rapist. I think whether they are or aren't meant to be taken literally, this album concept is gonna turn off a lot of people. I think Hayden is very aware of that and that it was potentially intentional.

The response to the announcement of Perverts online, specifically on TikTok, has confused me. I did not expect to see so many people surprised and even disgusted by the simple title of the album. Claiming that it's gone a step too far, or it's going to be hard to repost or interact with an album called 'Perverts' is very telling of how few people have actually analyzed or sincerely engaged with hayden's previous works. Of course it's okay to lightheartedly enjoy a piece of media, but an unconventional album title should be nothing surprising based on the topics hayden has an affinity for discussing. Perverts is going to be heavy and it's going to be dark, but so was Preacher's Daughter, Inbred, Golden Age, and Carpet Beds. The simplification of these works deeply saddens me. Why should anyone's main focus when enjoying a piece of media be the thought of how much online interaction it will get when you post about it?

Pinterest Boosts Service Reliability by Overcoming AWS EC2 Network Throttling

Pinterest, a platform synonymous with creativity and inspiration, relies heavily on robust infrastructure to deliver seamless user experiences. However, like many tech giants, it faced significant challenges with AWS EC2 network throttling, which threatened service reliability. Overcoming AWS EC2 network throttling became a critical mission for Pinterest’s engineering team to ensure uninterrupted access for millions of users. This blog explores how Pinterest tackled this issue, optimized its cloud infrastructure, and boosted service reliability while maintaining scalability and performance.

Understanding AWS EC2 Network Throttling

AWS EC2 (Elastic Compute Cloud) is a cornerstone of modern cloud computing, offering scalable virtual servers. However, one limitation that organizations like Pinterest encounter is network throttling, where AWS imposes bandwidth limits on EC2 instances to manage resource allocation. These limits can lead to performance bottlenecks, especially for high-traffic platforms handling massive data transfers.

What Causes Network Throttling in AWS EC2?

Network throttling in AWS EC2 occurs when an instance exceeds its allocated network bandwidth, which is determined by the instance type and size. For example, smaller instances like t2.micro have lower baseline network performance compared to larger ones like m5.large. When traffic spikes or data-intensive operations occur, throttling can result in packet loss, increased latency, or degraded user experience.

Why Pinterest Faced This Challenge

Pinterest’s platform, with its image-heavy content and real-time user interactions, demands significant network resources. As user engagement grew, so did the strain on EC2 instances, leading to throttling issues that impacted service reliability. The need to address this became urgent to maintain Pinterest’s reputation for fast, reliable access to visual content.

Strategies Pinterest Employed to Overcome Throttling

To tackle AWS EC2 network throttling, Pinterest adopted a multi-faceted approach that combined infrastructure optimization, advanced monitoring, and strategic resource allocation. These strategies not only mitigated throttling but also enhanced overall system performance.

Optimizing Instance Types for Network Performance

One of Pinterest’s first steps was to reassess its EC2 instance types. The team identified that certain workloads were running on instances with insufficient network bandwidth.

Upgrading to Network-Optimized Instances

Pinterest migrated critical workloads to network-optimized instances like the C5 or R5 series, which offer enhanced networking capabilities through Elastic Network Adapter (ENA). These instances provide higher baseline bandwidth and support features like Enhanced Networking, reducing the likelihood of throttling during peak traffic.

Rightsizing Instances for Workloads

Rather than over-provisioning resources, Pinterest’s engineers conducted thorough workload analysis to match instance types to specific tasks. For example, compute-intensive tasks were assigned to C5 instances, while memory-intensive operations leveraged R5 instances, ensuring optimal resource utilization.

Implementing Advanced Traffic Management

Effective traffic management was crucial for overcoming AWS EC2 network throttling. Pinterest implemented several techniques to distribute network load efficiently.

Load Balancing with AWS Elastic Load Balancer (ELB)

Pinterest utilized AWS ELB to distribute incoming traffic across multiple EC2 instances. By spreading requests evenly, ELB prevented any single instance from hitting its network limits, reducing the risk of throttling. The team also configured Application Load Balancers (ALB) for more granular control over HTTP/HTTPS traffic.

Auto-Scaling for Dynamic Traffic Spikes

To handle sudden surges in user activity, Pinterest implemented auto-scaling groups. These groups automatically adjusted the number of active EC2 instances based on real-time demand, ensuring sufficient network capacity during peak periods like holiday seasons or viral content surges.

Enhancing Monitoring and Alerting

Proactive monitoring was a game-changer for Pinterest in identifying and addressing throttling issues before they impacted users.

Real-Time Metrics with Amazon CloudWatch

Pinterest leveraged Amazon CloudWatch to monitor network performance metrics such as NetworkIn, NetworkOut, and Packet Loss. Custom dashboards provided real-time insights into instance health, enabling engineers to detect throttling events early and take corrective action.

Custom Alerts for Throttling Thresholds

The team set up custom alerts in CloudWatch to notify them when network usage approached throttling thresholds. This allowed Pinterest to proactively scale resources or redistribute traffic, minimizing disruptions.

Leveraging VPC Endpoints and Direct Connect

To further reduce network bottlenecks, Pinterest optimized its AWS network architecture.

Using VPC Endpoints for Internal Traffic

Pinterest implemented AWS VPC Endpoints to route traffic to AWS services like S3 or DynamoDB privately, bypassing public internet routes. This reduced external network dependency, lowering the risk of throttling for data-intensive operations.

AWS Direct Connect for Stable Connectivity

For critical workloads requiring consistent, high-bandwidth connections, Pinterest adopted AWS Direct Connect. This dedicated network link between Pinterest’s on-premises infrastructure and AWS ensured stable, low-latency data transfers, further mitigating throttling risks.

The Role of Caching and Content Delivery

Pinterest’s image-heavy platform made caching and content delivery optimization critical components of its strategy to overcome network throttling.

Implementing Amazon CloudFront

Pinterest integrated Amazon CloudFront, a content delivery network (CDN), to cache static assets like images and videos at edge locations worldwide. By serving content closer to users, CloudFront reduced the network load on EC2 instances, minimizing throttling incidents.

In-Memory Caching with Amazon ElastiCache

To reduce database query loads, Pinterest used Amazon ElastiCache for in-memory caching. By storing frequently accessed data in Redis or Memcached, Pinterest decreased the network traffic between EC2 instances and databases, improving response times and reducing throttling risks.

Measuring the Impact of Pinterest’s Efforts

After implementing these strategies, Pinterest saw significant improvements in service reliability and user experience.

Reduced Latency and Improved Uptime

By optimizing instance types and leveraging advanced traffic management, Pinterest reduced latency by up to 30% during peak traffic periods. Uptime metrics also improved, with fewer incidents of downtime caused by network throttling.

Cost Efficiency Without Compromising Performance

Pinterest’s rightsizing efforts ensured that resources were used efficiently, avoiding unnecessary costs. By choosing the right instance types and implementing auto-scaling, the company maintained high performance while keeping infrastructure costs in check.

Enhanced User Satisfaction

With faster load times and fewer disruptions, Pinterest users reported higher satisfaction. The platform’s ability to handle traffic spikes during major events, like seasonal campaigns, strengthened its reputation as a reliable service.

Lessons Learned from Pinterest’s Approach

Pinterest’s success in overcoming AWS EC2 network throttling offers valuable lessons for other organizations facing similar challenges.

Prioritize Proactive Monitoring

Real-time monitoring and alerting are essential for identifying potential throttling issues before they impact users. Tools like CloudWatch can provide the insights needed to stay ahead of performance bottlenecks.

Balance Scalability and Cost

Choosing the right instance types and implementing auto-scaling can help organizations scale resources dynamically without overspending. Rightsizing workloads ensures cost efficiency while maintaining performance.

Leverage AWS Ecosystem Tools

AWS offers a suite of tools like ELB, CloudFront, and VPC Endpoints that can significantly reduce network strain. Integrating these tools into your architecture can enhance reliability and performance.

Future-Proofing Pinterest’s Infrastructure

As Pinterest continues to grow, its engineering team remains focused on future-proofing its infrastructure. Ongoing efforts include exploring serverless architectures, such as AWS Lambda, to offload certain workloads from EC2 instances. Additionally, Pinterest is investing in machine learning to predict traffic patterns and optimize resource allocation proactively.

Adopting Serverless for Flexibility

By incorporating serverless computing, Pinterest aims to reduce its reliance on EC2 instances for specific tasks, further minimizing the risk of network throttling. Serverless architectures can scale automatically, providing a buffer against sudden traffic spikes.

Predictive Analytics for Resource Planning

Using machine learning models, Pinterest is developing predictive analytics to forecast user activity and allocate resources accordingly. This proactive approach ensures that the platform remains resilient even during unexpected surges.

Overcoming AWS EC2 network throttling was a pivotal achievement for Pinterest, enabling the platform to deliver reliable, high-performance services to its global user base. By optimizing instance types, enhancing traffic management, leveraging caching, and adopting proactive monitoring, Pinterest not only addressed throttling but also set a foundation for future scalability. These strategies offer a blueprint for other organizations navigating similar challenges in the cloud, proving that with the right approach, even the most complex infrastructure hurdles can be overcome.

Future-dated Capacity Reservations For AWS EC2 On-Demand

Declaring future-dated Capacity Reservations for Amazon EC2 On-Demand Capacity

Amazon Elastic Compute Cloud (EC2) is used for databases, virtual desktops, big data processing, web hosting, HPC, and live event broadcasting. Customers requested the flexibility to reserve capacity for certain workloads because they are so important.

In 2018, EC2 On-Demand Capacity Reservations (ODCRs) were introduced to enable users to reserve capacity flexibly. Customers have since utilized capacity reservations (CRs) to run vital services such as processing financial transactions, hosting consumer websites, and live-streaming sporting events.

Today, AWS reveals that CRs can be used to determine the capacity for upcoming workloads. Many customers anticipate future events, such as product releases, significant migrations, or end-of-year sales occasions like Diwali or Cyber Monday. Since these events are crucial, customers want to be sure they have the capacity when and where they need it.

CRs were only available just-in-time, but they assisted clients in reserving capacity for certain events. Customers were therefore need to either carefully prepare to provision CRs just-in-time at the beginning of the event or provision the capacity in advance and pay for it.

Your CRs can now be planned and scheduled up to 120 days ahead of time. To begin, you provide the amount of capacity you require, the start date, your preferred delivery method, and the minimum amount of time you are willing to use the capacity reservation. Making a capacity reservation doesn’t cost anything up ahead. Following evaluation and approval of the request, Amazon EC2 will activate the reservation on the start date, allowing users to begin instances right away.

Beginning to make future-dated Capacity Reservations

Select Capacity Reservations in the Amazon EC2 console, then click Create On-Demand Capacity Reservation and click Get Started to reserve your future-dated capacity.

Indicate the instance type, platform, Availability Zone, platform, tenancy, and quantity of instances you want to reserve in order to create a capacity reservation.

Select the Capacity Reservation information section. Choose your start date and commitment period later on in the Capacity Reservation starts option.

Additionally, you can decide to manually or at a specified time terminate the capacity reserve. The reservation has no expiry date if you choose Manually. Unless you actively cancel it, it will stay in your account and keep getting billed. Click Create to reserve this capacity.

Your capacity request will show up in the dashboard with an Assessing status after it has been created. AWS systems will try to ascertain whether your request is supportable during this phase, which typically takes five days. The status will be changed to Scheduled as soon as the systems decide the request is feasible. Rarely, your request might not be able to be supported.

The capacity reserve will become Active on the day you have chosen, the total number of instances will be raised to the desired number, and you will be able to start instances right away.

You have to keep the reservation for the minimum amount of time specified when it is activated. You have the option to either cancel the reservation if it is no longer needed or keep it and use it if you would like after the commitment period has passed.

Things to consider

The following information concerning the future-dated Capacity Reservations is important for you to know:

Evaluation: When assessing your request, Amazon EC2 takes into account several parameters. In addition to the anticipated supply, Amazon EC2 considers the size of your request, the length of time you intend to hold the capacity, and how early you make the capacity reservation about your start date. Create your reservation at least 56 days (8 weeks) before the commencement date to increase Amazon EC2’s capacity to fulfill your request. For instance types C, M, R, T, and I only, you must require a minimum of 100 virtual CPUs. For the majority of requests, a 14-day minimum commitment is advised.

Notification: It suggests using the console or Amazon EventBridge to keep an eye on the progress of your request. These alerts can be used to send an email or SMS update or to start an automation process.

Cost: Future-dated capacity reservations are charged in the same way as standard CRs. Whether you run instances in reserved capacity or not, you are still charged the same On-Demand fee. For instance, you will be charged for 15 active instances and 5 unused instances in the reservation, including the minimum period, if you establish a future-dated CR for 20 instances and operate 15 instances. Both instances that are operating on the reservation and reservations that are not being used are covered by savings plans.

Currently offered

In all AWS regions where Amazon EC2 Capacity Reservations are available, EC2 future-dated Capacity Reservations are now accessible. Try Amazon EC2 Capacity Reservations in the Amazon EC2 console.
