Downtime is expensive, and it’s getting harder to avoid. Every year, enterprise IT environments grow more distributed, dynamic, and difficult to maintain with legacy tools and manual processes. With unplanned outages costing enterprises nearly $25,000 per minute, establishing and maintaining a resilient IT infrastructure is essential. Enterprises have already invested heavily in resilient architecture.

High availability (HA) is a system’s ability to keep serving users when individual components fail, from a single server up to a whole cloud region or provider. It is measured in nines: 99.9% allows about 8 hours 46 minutes of downtime a year, 99.99% about 52 minutes, and 99.999% about 5 minutes 15 seconds. HA works by removing single points of failure through redundancy, health checks, automatic failover, and replicated data.

CloudWatch already holds the lines from your Lambda, ECS task, or unified agent. The first useful win on Logit.io is not a migration spreadsheet. It is one Log Group, the documented Lambda shipper posting to this stack's API, and rows in OpenSearch Dashboards Discover that show logGroupName, logStreamName, and message. If you are still proving that a Logs stack can accept anything at all, start with First Logs on Logit.io; this post assumes CloudWatch is the source and the Stack API is the pipe. Contents.

RMM lets one small team look after thousands of machines nobody will ever physically touch. It grew up inside managed service providers. The whole category runs on agent-based monitoring, which means a small program sits on every endpoint and phones home on a schedule. That agent is also why attackers have taken such an interest lately. In this blog, you'll see: By the end you'll know what the category covers and where it stops. RMM stands for remote monitoring and management.

Why would a website that passes every uptime check still show customers a security warning? In most cases, the server is running and the network is healthy. The failure happens earlier, during the brief exchange in which the browser and the server agree on how to communicate securely. That moment is the SSL handshake. If it goes wrong, users get an error page while your dashboards stay green. Maybe a certificate expired; maybe a routine change left both sides on different protocol versions.

Last updated: October 9, 2026 A zero-day vulnerability may be unknown, but its effects often are not. Exploitation can leave behind observable changes: a new privileged account, an altered management setting, an unexpected file, a modified access rule, or configuration drift from an approved baseline. That makes zero-day configuration monitoring an important part of a defense-in-depth strategy.

Top tips is a weekly column where we highlight what’s trending in the tech world and share ways to stay ahead. This week, we’re looking at what you can when you’re having a slow-paced, less hectic workweek. We’ve all been there at intermittent intervals of our jobs: You check into the office right after the weekend only to realize you’re having one of those slow, relatively low-pressure weeks. So what do you do to stay productive?

The moment your page slows down, two clocks start. One is yours: time to alert, time to investigate, time to fix. The other belongs to the user staring at the slow page. Yours is measured in minutes. Theirs runs out in seconds. That gap is what AI agents close. Zia Agents in OpManager Nexus detects an issue, works out the cause, and runs the fix on its own, often before your users feel a thing. This blog looks at how that changes the experience you deliver.

Building and managing hybrid cloud infrastructure is an increasingly common requirement for engineering teams. Some companies want to cut hyperscaler costs. Others have business continuity requirements that mean spreading infrastructure across several providers. Either way, more teams are taking hybrid cloud management into their own hands.
