Global Capacity Optimization for a Faster and More Reliable Network

Global Capacity Optimization is key to a faster and more reliable network. By analyzing traffic patterns and optimizing capacity, service providers can ensure that their networks can handle the increasing demand for data and applications.

According to a study, the average global internet traffic is projected to grow by 30% annually. This growth can be attributed to the increasing number of connected devices and online applications.

Optimizing capacity requires a thorough understanding of network traffic patterns. By analyzing traffic patterns, service providers can identify areas where capacity needs to be increased or optimized.

In some regions, the demand for data is outpacing the available capacity. This can lead to slower speeds and a poor user experience.

Global Capacity has made several strategic acquisitions to expand its network and services.

In 2016, the company acquired Internap's Network Services division, which added 4,000 on-net buildings and 12,000 route miles to Global Capacity's network.

This acquisition marked a significant milestone in the company's growth and expansion.

The acquisition of Internap's Network Services division provided Global Capacity with a stronger presence in the enterprise market.

Global Capacity has also formed partnerships with other companies to enhance its services and reach.

One notable partnership is with the global telecommunications company, Orange Business Services.

We need to rethink our approach to capacity management as we prepare for a growing number of regions with different failure characteristics.

Continuous evolution of disaster-readiness strategy is key to adapting to changing needs, starting with changing how we plan for disaster-readiness buffer capacity.

Many systems today provide only regional abstractions, which limits an infrastructure's ability to automate movements across regions.

Service owners often hard-code specific regions and manually compute capacity required to be disaster-ready, without considering the bigger picture.

Our infrastructure provides less flexibility for shifting capacity across regions to optimize for different goals or to be more efficient due to a lack of understanding of service owners' intentions.

At Meta, we realized the need for a holistic solution and developed a longer-term vision of transparent, automated global-capacity management.

Latency-tolerant services are easily movable in isolation, making them ideal for Global Reservations.

For latency-sensitive services, placement requirements must be considered to reduce cross-region network requests. This involves attributing demand for the services and modeling them to understand latency and geographic distribution requirements.

Latency-sensitive services demand a fast response time, and their placement must consider the placement of upstream and downstream dependencies to minimize latency.

Latency-tolerant services power products that can handle a slight delay in fulfilling requests, such as uploading a large file. These services are easily movable in isolation.

Latency-sensitive services, on the other hand, require a fast response time, like viewing photos or videos on social media apps. They have placement requirements to reduce and/or eliminate cross-region network requests.

Most latency-sensitive services need to be placed near their upstream and downstream dependencies to minimize latency. This is because these services demand a fast response time.

Here are the two common service types:

Latency-tolerant services do not have the constraint of being placed near their dependencies, making it easier to manage their capacity. The Global Reservations Service simplifies capacity management for these services.

Regional Fluidity is used to rebalance latency-sensitive services by redistributing the demand source. This system safely moves services toward a globally optimized state.

We help reduce latency by optimizing network protocols, which can be up to 30% slower due to unnecessary packet retransmissions.

Our team of experts analyzes network traffic patterns to identify bottlenecks and areas for improvement.

By implementing content delivery networks (CDNs), we can reduce latency by up to 50% by caching frequently accessed content closer to users.

We also work with clients to ensure their websites are properly optimized for fast loading times, which can result in a 2-3 second improvement in load times.

By minimizing the number of requests made to a server, we can reduce latency and improve the overall user experience.

As you navigate the complex world of renewable energy, there are a few key things to keep in mind. One of the most important is the diversity of sources that make up the total renewable energy mix.

There are many types of renewable energy sources, including bioenergy, geothermal, hydropower, and solar. In fact, the total renewable energy installed capacity includes bioenergy, geothermal, hydropower (excluding pumped storage), solar, wind, and marine energy.

Let's take a closer look at some of the specific types of renewable energy sources. Bioenergy, for example, includes biogas, liquid biofuels, solid biofuels, and renewable municipal waste. Geothermal energy, on the other hand, is a reliable source of power that can be harnessed from the heat of the Earth.

Here are some of the key types of renewable energy sources and their installed capacities:

It's worth noting that the installed capacity of renewable energy sources can vary significantly depending on the type of source and the location. For example, the installed capacity of solar energy is typically much higher in sunny regions than in cloudy ones.

Global reservations help simplify global service management by automatically adding and resizing disaster-readiness buffers over time to provide fault tolerance for latency-tolerant services.

To ensure efficient capacity allocation, service owners can encode their intent in global reservations, which are declarative and intent-based. This approach allows the infrastructure to improve placement over time while still satisfying the service owner's intent.

Service capacity requirements are related to demand sources, such as users of the Facebook app and users of the Instagram app. To minimize user latency, the news feed services must be located in the same regions as the application front-end services that handle requests from the demand sources.

Here are the attribution steps for demand sources:

Understanding demand sources is crucial to managing traffic and allocating capacity effectively. This involves attributing demand sources to specific regions and services.

We use a distributed tracing framework to quantify demand source attribution, which can determine the origin of requests from different demand sources. For example, a request from the Instagram demand source may call the IG service, which then calls the Foo service.

Each demand source can be shifted independently, allowing us to control the distribution of requests to each region from different demand sources.

Once a request from a demand source enters a region, the request typically must finish within that region or enter another independently shiftable demand source.

Here are the key steps in attributing demand sources:

The Global Reservations Service uses a format where machines are assigned to global reservations, enabling the encoding of various constraints and objectives.

In this format, rows correspond to machines and columns to global reservations, with each entry containing an assignment variable X (either 0 or 1) that indicates whether that machine is assigned to that global reservation.

Because we can assign a machine to exactly one global reservation, the variables in the red row must add up to 1.

This is crucial for ensuring that each machine is assigned to only one global reservation.

The variables in the green column must equal the sum of at least the amount requested by Global Reservation 0, to fulfill the request.

To provide fault tolerance, the total number of machines assigned to a global reservation minus the amount in the largest region for that reservation must be at least the amount requested by the global reservation.

This ensures that if one region becomes unavailable, the other regions can still fulfill the request.

The Solver optimizes for various objectives, such as minimizing the total number of allocated servers in the fleet, by translating other types of constraints and objectives into a mixed-integer linear programming problem.

Regional planning and optimization are crucial components of global capacity management. By understanding the demand for services and attributing that demand to specific regions, we can rebalance services and redistribute capacity across regions.

Regional Fluidity allows us to safely move services to globally optimized states by redistributing demand sources. This process involves modeling services and understanding demand, which enables us to use regional fluidity to rebalance services.

To safely shift demand sources, we must add additional capacity in the target region, increase traffic, and decrease traffic in the source region. This process involves several steps, including adding replicas of Twine jobs and reclaiming capacity in the source region.

Here's a breakdown of the steps involved in shifting demand sources:

Regional Fluidity provides several benefits, including homogenization of the hardware footprint, safe redistribution of service capacity, and global optimization. By automating the process of shifting demand sources, we can improve global efficiency and reduce the amount of stranded power caused by mismatches between service needs and regional hardware footprints.

The Solver, a key component of Regional Fluidity, produces a placement plan for various demand sources by using service dependencies and traffic ratios as constraints. The Solver then considers the constraints, optimization functions, demand attribution, and supply to generate a feasible plan.

The Orchestrator, another crucial component, executes the placement plan generated by the Solver. The Orchestrator drives the execution of the plan from end to end, sequencing various actions to ensure the safety of all services at all times.
