What is Memcached?

The memcached image packages the memcached daemon - a simple, in-memory, distributed key-value cache used to speed up dynamic web applications by reducing database load. Unlike Redis, memcached focuses on a single use case: a fast volatile cache. It has no persistence, no complex data structures, and excellent multi-threaded performance for cache-heavy workloads.

What is Echo's Memcached image?

Echo's memcached image is a hardened build of the memcached daemon. Echo images are designed to be a drop-in replacement: change the FROM line in your Dockerfile and CVEs go to zero without breaking your app. Every image is tested across clouds, image use cases, and deployment targets. Echo ships every image in two variants: a distroless variant optimized for runtime use, and a default variant that includes essential build tools, package managers, and shells. The distroless variant is particularly suited to memcached because it has very few external dependencies - most of what's in a typical public memcached image is OS bloat, not memcached itself.

What is the difference between Echo's Memcached image and the public Memcached image?

Public memcached images carry an OS layer many times the size of the memcached binary, and that OS layer brings most of the CVEs. Echo's image is reduced to the essentials, dropping CVE counts to zero. Echo commits to a 7-day SLA for critical and high severity vulnerabilities, and 10 days for medium, low, and unknown - with vulnerabilities triaged within 24 hours. Echo images are recognized by all major scanners and mirrored to all major registries, so they fit into existing pipelines without changing your registry, scanner, or runtime tooling.

FAQ

Can I replace my memcached image with Echo's memcached image?

Yes. Echo's memcached image is a drop-in replacement. Update the FROM line in your Dockerfile (or the image reference in your manifests) and your application keeps working - the CVEs disappear, the behavior doesn't.

Is Echo's memcached image FIPS-validated?

Yes. Echo's FIPS-validated images use cryptographic modules with an active FIPS 140-3 CMVP certificate, making them fit for federal use - unlike FIPS-compliant images that haven't been validated.

What is Echo's vulnerability management SLA on the memcached image?

Echo commits to a 7-day SLA for critical and high severity vulnerabilities, and 10 days for medium, low, and unknown - with vulnerabilities triaged within 24 hours. Patches are mirrored automatically into your private registry so you're always running a clean version.

Is Echo's memcached image distroless?

Echo ships every image in two variants: a distroless variant optimized for runtime use, and a default variant that includes essential build tools, package managers, and shells.

How does Echo achieve such a drastic CVE reduction in memcached?

Echo memcached is built from source with only the absolute essentials needed to run the workload, which significantly shrinks the attack surface. Echo also patches aggressively over time, with backports available so you can stay on the version that works for you without forcing a functional change for the sake of security.

Will Echo's memcached image help us achieve FedRAMP?

Yes. The hard parts of FedRAMP - managing vulnerabilities, applying fixes, and using FIPS-validated cryptography - are baked into Echo images, including STIG-hardened configuration and ConMon/POA&M-ready reporting.
