Every project is tailored, with the architecture and acceptance criteria defined up front, so that growing doesn't mean going down. quoted after assessment Updated on October 27, 2026 ![Traffic reaches a distribution point that spreads the load across several servers, with one more server being added.](https://workinprogress.company/_astro/servico-scale.INmhn7lL_iOq61.png) ## How do you know if a system needs to be prepared for scale? A system needs preparation when expected demand is higher than its measured capacity, or when nobody knows what that capacity is. The signs show up before an outage, at peak times, for anyone who is watching. Warning signs: - response times climb sharply during the busiest hours; - the database gets close to its connection or CPU limit; - heavy tasks, such as generating reports or sending bulk email, slow down the rest of the system; - there is a single server, and if it stops, everything stops; - a campaign, a launch, or a big client will multiply traffic on a known date. It is also worth preparing when the business moves up a level: a contract that requires a minimum level of availability, an expansion into new markets, or an integration with partners who send large volumes of data. The first step is to measure. A load test in a controlled environment shows how much the system can handle today and which part gives way first. Sometimes the answer is reassuring, and the project ends there, with a report. Sometimes it reveals a concrete bottleneck, and then the work has a clear target. ## How does a scale readiness project work? The project defines the target first and the architecture second: how much the system needs to handle, with what response time and what error rate. Those targets become acceptance criteria, verified with tests at the end. ### Steps 1. **Measuring the current state**, with a load test and an analysis of the bottlenecks. 2. **Acceptance criteria**, agreed with you: traffic volume, response time, and expected behavior when something fails. 3. **Proposed architecture**, with the least complexity that meets the criteria and the estimated monthly infrastructure cost. 4. **Implementation**, in stages and with a way back. 5. **Load and recovery tests**, to show that the criteria were met. ### Techniques that may be used - **Caching**, so that what rarely changes is not recalculated. - **Queues**, to move heavy tasks out of the user’s way. - **Load balancing**, to split traffic across servers. - **Database replication**, when reads are the bottleneck or recovery requires it. - **Redundancy**, to remove single points of failure. Not every project uses all of them. The choice depends on the measured bottleneck, not on a ready-made recipe. ## Does scaling always increase infrastructure costs? Not necessarily. Some changes reduce costs, such as a cache that takes load off the database; others increase them, such as keeping redundant servers ready to take over if something fails. What matters is that the trade-off is explicit. For each change, the proposal shows what it solves, how much it costs per month, and the risk of not doing it. That makes it a business decision: redundancy is worth paying for when being offline costs more than it does. A few principles guide our recommendations: - **Scale the bottleneck, not the whole system.** If the problem is the database, adding application servers only increases the bill. - **Prefer elasticity over idle capacity.** When the infrastructure allows it, capacity grows at peak times and shrinks afterward. - **Simplicity first.** Distributed architectures require more operations work, more monitoring, and more expertise from whoever maintains them. They are only worth it when demand justifies them. - **Measure afterward.** The actual cost is tracked after delivery to confirm it stayed within the estimate. As with all WIP services, infrastructure is listed separately from the project fee, and the choice of provider follows what the system needs, not a commercial preference. ## What does WIP Scale deliver? - Assessment of current capacity and of the points that give way first under load. - Proposed architecture, with measurable acceptance criteria. - Implementation of load balancing, queues, caching, and replication, as needed. - Redundancy and a tested recovery procedure. - Load tests before and after the changes. ## Who is WIP Scale for? - Products about to face a campaign, a launch, or the arrival of a big client. - Systems that already struggle at peak times. - Businesses that need to eliminate single points of failure. ## What is not included in WIP Scale? - Unnecessary complexity: replication and redundancy are added only when demand and risk justify them. - A promise of absolute availability: the system's limits are measured and reported to you. - Additional infrastructure costs, which are kept separate from WIP's fees. ## How much does WIP Scale cost? WIP Scale is quoted after a technical assessment. Tailored project: the price depends on the current architecture, the expected demand, and the acceptance criteria. Infrastructure, licenses, and third-party services are charged separately. ## Frequently asked questions about WIP Scale ### How much does it cost to prepare a system to scale? WIP Scale is a tailored project. The price depends on the current architecture, the expected demand, and the agreed acceptance criteria, and it is presented in the proposal before work starts. Additional infrastructure is charged separately and kept apart from WIP's fees. ### Do I need Kubernetes to scale? Not necessarily. The choice depends on actual demand, who will operate the system, and cost. Sometimes a well-sized server with caching and queues is enough; other times it pays to spread the load across several machines. WIP recommends the least complexity that meets the acceptance criteria. ### How do I know how much load my system can handle today? With a load test. The expected traffic is simulated in a controlled environment, and response time, error rate, and resource usage are measured until we find the point where the system starts to give way. ### What are acceptance criteria? They are measurable targets that define when the project is done, such as handling a given volume of concurrent users with response time and error rate within agreed limits. They are set before implementation and verified with tests at the end. ## Related services Performance and costs ### [WIP Optimize](https://workinprogress.company/services/performance-and-costs) The system works, but it slows down when it matters most or costs more than it should. quoted after assessment Mission-critical operations ### [WIP Mission Critical](https://workinprogress.company/services/mission-critical) Downtime or data loss costs your business too much to leave to improvisation. quoted after assessment Managed operations ### [WIP Managed](https://workinprogress.company/services/managed-operations) Your systems run the business, but nobody is there to oversee them, plan ahead, and make changes safely. starting at US$ 470 per month ## Start with a diagnosis Before investing in changes, understand the risks, bottlenecks and waste in your system.
