Velstash Cache

Velstash Cache provides developers and small teams with dedicated, managed memcached instances that eliminate the complexity of traditional caching infrastructure. Instead of wrestling with cluster configurations, capacity planning, and unexpected costs, you get a network-reachable cache sized exactly to your memory requirements.

What It Does

Velstash delivers a dedicated cache instance accessible over the standard memcached protocol. This means existing memcached clients work without any modifications. The service handles all the underlying infrastructure management, allowing you to focus on your application rather than cache maintenance. Hosted in Europe with datacenters in France and Finland, the service provides low-latency access for European users while planning expansion to additional regions.

Key Features

• Dedicated instances: Each customer receives their own isolated cache instance, ensuring consistent performance without noisy neighbor problems or shared resource contention.

• European hosting: Infrastructure hosted in France and Finland, with additional regions planned for the future to serve a broader global audience.

• Comprehensive dashboard: Real-time visibility into cache performance including hit rates over 5, 10, and 15 minute windows, memory usage, item counts, active connections, and evictions.

• Historical analytics: View performance trends across multiple timeframes from 1 hour to 30 days, with separate tracking for memory usage, hit rate, item count, evictions per second, and worker count.

• Latency monitoring: Read and write latency tracked separately with P50, P90, and P99 percentiles displayed as line charts and broken down into average milliseconds in a detailed table.

• Top keys and prefixes: Analyze caching strategy effectiveness by examining hit and miss statistics broken down by prefix and individual key across different timeframes.

• Alerts system: Email notifications when memory usage or hit rate falls outside configured thresholds, enabling proactive cache management.

• Credentials management: Different permissions per environment or application, allowing read-only access for some services while preventing cache flushes from others.

• Per-slab breakdown: Detailed view showing exactly where memory is allocated across different slab classes, helping optimize storage efficiency.

Who It Is For

Velstash Cache is built for developers and small teams who want caching infrastructure to be a solved problem rather than a month-long project. It is ideal for those who need reliable memcached without the overhead of managing clusters, dealing with complex cloud provider configurations, or navigating confusing pricing structures. Whether you are running a web application, API service, or any system that benefits from caching, Velstash provides the infrastructure without the headaches.

Why It Stands Out

Unlike major cloud providers that require VPC setup, subnet configuration, and reserved-instance commitments, Velstash offers a straightforward approach to caching. The service leverages bare-metal infrastructure and long-term capacity commitments to provide reliable performance without the complexity or overhead of traditional cloud caching services.

The comprehensive monitoring capabilities set Velstash apart from simpler caching solutions. With millisecond-level latency tracking, you can identify performance issues before they impact users. The per-slab breakdown shows exactly where memory is being allocated, helping you optimize your caching strategy and storage efficiency.

The credentials management system enables fine-grained access control, allowing different applications to have different permissions. An application might be allowed only to read from the cache, or prevented from flushing the entire cache, providing security and control in multi-application environments.

With no cluster tuning required and no capacity planning spreadsheets to maintain, Velstash Cache transforms caching from an infrastructure challenge into a simple, managed service that scales with your needs. The straightforward approach means you can spin up a cache instance in minutes and start improving your application performance immediately.
