Global Capacity Planning and Optimization

Global Capacity Planning and Optimization is a crucial aspect of managing global capacity effectively. This involves analyzing and optimizing the capacity of various systems, networks, and resources to ensure they meet the demands of a growing business.

With the right capacity planning and optimization strategies, businesses can reduce waste and improve efficiency by up to 30%. This can be achieved by identifying and eliminating bottlenecks in the supply chain, streamlining processes, and investing in technology that automates tasks.

Effective capacity planning and optimization also enables businesses to respond quickly to changes in demand and supply, reducing the risk of stockouts and overstocking. By doing so, companies can maintain high levels of customer satisfaction and loyalty.

By implementing robust capacity planning and optimization techniques, businesses can unlock new revenue streams and improve their bottom line. This can be achieved by leveraging data analytics to forecast demand and optimize production levels, resulting in cost savings and increased profitability.

To manage global capacity, we need to rethink our approach to capacity management, transforming it to be more disaster-ready and adaptable to different regions' failure characteristics.

Continuous global-capacity management is crucial for optimizing performance and efficiency. At Meta, we recognized the need for a more holistic approach, developing a longer-term vision for transparent and automated global-capacity management.

The process of planning capacity involves understanding service latency and geographic distribution requirements, which is modeled using solvers that address global placement problems. These solvers honor constraints and optimize global objectives.

Regional Fluidity introduces automation to rebalance services across regions and redistribute demand driving these services. This automation is crucial for safe and efficient regional capacity shifts.

Here are the key elements of Regional Fluidity:

These elements work together to provide first-class fluidity, allowing for safe and efficient global capacity management.

As we prepare for a growing number of regions with different failure characteristics, we have to transform our approach to capacity management.

The solution starts with continuously evolving our disaster-readiness strategy and changing how we plan for disaster-readiness buffer capacity. We need to redistribute capacity more often to increase volume in new regions, as well as more frequent hardware decommissions and refreshes. Many of today's systems provide only regional abstractions, which limits an infrastructure's ability to automate movements across regions.

We often don't know service owners' intentions for using specific regions, resulting in less flexibility for shifting capacity across regions to optimize for different goals or to be more efficient. At Meta, we realized we needed to start thinking more holistically about the solution and develop a longer-term vision of transparent, automated global-capacity management.

Building on top of regional capacity management foundations, we created Global Reservations to provide strong guarantees about the placement of capacity. This allows service owners to reason about their capacity - globally and with guarantees.

Scale shift planning is a complex process that requires careful consideration of multiple factors. It involves assigning capacity to services in specific regions to ensure safe and efficient operation.

To make regional capacity shift plans at scale, we need an automated solution that can model service latency and geographic distribution requirements. This involves using solvers to address global placement problems and honoring constraints and optimizing global objectives.

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

Regional Fluidity introduces several new elements to provide first-class fluidity, including modeling, solvers, and automation. These elements enable us to rebalance services across regions and redistribute demand driving these services.

Here are the key steps involved in shifting a demand source from one region to another:

By following these steps, we can ensure that both regions maintain a safe state during the shift. This process is critical for managing global capacity and ensuring efficient operation of our infrastructure.

The Global Reservations Service models the assignment of machines to global reservations as a bin-packing problem, where machines are assigned to global reservations in a way that minimizes waste and optimizes resource utilization.

This approach enables the encoding of various constraints and objectives, such as ensuring that enough machines are assigned to fulfill a request, and providing fault tolerance if a region becomes unavailable.

In this format, each entry in a table represents an assignment variable, indicating whether a machine is assigned to a global reservation. The variables in the red row must add up to 1, since a machine can be assigned to exactly one global reservation.

The variables in the green column must equal the sum of at least the amount requested by a global reservation, ensuring that enough machines are assigned to fulfill the request.

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, providing fault tolerance if a region becomes unavailable.

For example, to minimize the total number of allocated servers in our fleet, the solver uses the following code:

The solver also translates other types of constraints and objectives into a mixed-integer linear programming problem, optimizing for various objectives such as minimizing the total number of allocated servers.

Latency-sensitive services demand a fast response time, such as viewing photos/videos on Facebook and Instagram mobile apps. They require placing services near their upstream and downstream dependencies to minimize latency.

Latency-tolerant services, on the other hand, can tolerate a slight delay in fulfilling requests, like uploading a large file or seeing a friend’s comments on a video.

To manage latency-sensitive services, we use Regional Fluidity to rebalance services by redistributing demand sources, ensuring a globally optimized state.

Regional Fluidity helps us model services and understand demand, making it easier to safely move services and reduce cross-region network requests.

Global Reservations, used for latency-tolerant services, automatically adds and resizes disaster-readiness buffers to provide fault tolerance, simplifying capacity management.

Here's a comparison of latency-sensitive and latency-tolerant services:

Regional Management is a crucial aspect of Global Capacity.

Previously, strong capacity management guarantees existed only at the regional level. Service owners had to monitor how much capacity to provision in each region for fault tolerance.

This led to increasingly complex fault tolerance and capacity reasoning for each region. As our scale continued to increase, we realized that this level of guarantee no longer provided the performance that our products required.

We created Global Reservations to give service owners a simpler way to reason about their capacity globally and with guarantees. Instead of creating individual reservations within each region, the service owner now creates a single global reservation.

The Global Reservation Service determines how much capacity is needed in each region. We can easily shift latency-tolerant services across regions to the placement that provides the performance necessary for continuous global optimization.

To meet a service owner's request for 300 servers in the North America continental locality, the Global Reservations Service provisions 150 servers each in three different regions, for a total of 450 servers.

Global capacity concepts are crucial in understanding how to scale and manage global services. Latency-sensitive services, such as viewing photos or videos on social media apps, demand a fast response time and require placement near upstream and downstream dependencies.

Latency-tolerant services, on the other hand, can tolerate a slight delay in fulfilling requests, such as uploading a large file or seeing a friend's comments on a video. These services can be placed anywhere without constraints.

To simplify capacity management for latency-tolerant services, Meta uses the Global Reservations Service, which automatically adds and resizes disaster-readiness buffers over time to provide fault tolerance.

The Global Reservations Service works by assigning machines to global reservations, which enables the encoding of various constraints and objectives. This process is done through a Solver that optimizes for various objectives, such as minimizing the total number of allocated servers in the fleet.

Here are the different types of constraints and objectives that the Solver considers:

By using global reservations, service owners can encode their intent and let the infrastructure optimize the placement over time, making it possible to optimize infrastructure for other objectives.

Global Reservations simplify reasoning about fault tolerance for service owners, automatically adding and resizing disaster-readiness buffers over time to provide fault tolerance.

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

These services can tolerate a slight delay in fulfilling requests, such as uploading a large file or seeing a friend's comments on a video.

Our Global Reservations Service is designed specifically for latency-tolerant services, providing a simplified capacity management solution.
