Roles change. Responsibilities change. Permissions should be reviewed too. #AccessManagement #EmmanueleTech30 Sep 2026 18:07 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwqwptprf22qhttps://bsky.app/profile/emmanueletech.com/post/3mwqeqe5ihk2pCreating a user account is easy. The bigger responsibility is managing that access as the person's role changes and eventually removing it when it is no longer needed. #ITAdministration #EmmanueleTech30 Sep 2026 12:45 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwqeqe5ihk2phttps://bsky.app/profile/emmanueletech.com/post/3mwoz2yawak2qAn application slows down every weekday around 9 AM, then recovers 30 minutes later. I wouldn’t immediately resize the server. That timing is a clue. I’d investigate what regularly happens during that window. #Troubleshooting #EmmanueleTech29 Sep 2026 23:44 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwoz2yawak2qhttps://bsky.app/profile/emmanueletech.com/post/3mwogzhgpts2rA metric is more useful when you know what normal looks like. CPU at 70 percent means more when you know whether the workload normally runs at 20 percent or 65 percent. Baselines matter. #CloudOperations #EmmanueleTech29 Sep 2026 18:21 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwogzhgpts2rhttps://bsky.app/profile/emmanueletech.com/post/3mwnv5aqsak2fWhen an application struggles, adding more CPU or memory might help. But I first want to know why it is struggling. More resources can sometimes hide the real problem. #CloudInfrastructure #EmmanueleTech29 Sep 2026 13:01 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwnv5aqsak2fhttps://bsky.app/profile/emmanueletech.com/post/3mwlei4eotk2aGood infrastructure shouldn’t depend on one person remembering everything. Another engineer should be able to understand the environment, the major decisions and how it is managed. #CloudInfrastructure #EmmanueleTech28 Sep 2026 12:57 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwlei4eotk2ahttps://bsky.app/profile/emmanueletech.com/post/3mwjwyfff4c27Users suddenly can’t access an application. I wouldn’t start making random changes. Confirm the impact, check logs and metrics, review recent changes and communicate while investigating. Calm troubleshooting matters. #IncidentResponse #EmmanueleTech27 Sep 2026 23:23 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwjwyfff4c27https://bsky.app/profile/emmanueletech.com/post/3mwiuftlcps2cIncident response isn’t only technical. While you investigate the problem, people also need to know what is happening. You may not have the answer yet, but you can communicate what you know. #ITOperations #EmmanueleTech27 Sep 2026 13:04 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwiuftlcps2chttps://bsky.app/profile/emmanueletech.com/post/3mwhlszovoc2lFive people need access to the same system. Would you make all five administrators? I wouldn’t. I’d first understand what each person actually needs to do and assign access around those responsibilities. #CloudSecurity #EmmanueleTech27 Sep 2026 00:58 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwhlszovoc2lhttps://bsky.app/profile/emmanueletech.com/post/3mwgvcwh2hs2tI don’t think everyone needs administrator access just because it makes things easier. Access should match responsibility. Give people what they need to do their work without giving away unnecessary control. #AccessManagement #EmmanueleTech26 Sep 2026 18:15 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwgvcwh2hs2thttps://bsky.app/profile/emmanueletech.com/post/3mwg7wfqji22qI prefer individual accounts over shared credentials. When everyone has their own identity, it becomes easier to understand who has access, who made a change and whose access should be removed. #CloudSecurity #EmmanueleTech26 Sep 2026 11:52 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwg7wfqji22qhttps://bsky.app/profile/emmanueletech.com/post/3mwf5nxfsas2rYou inherit an AWS environment you didn’t build. Everything works. Would you start changing things? I wouldn’t. First I’d understand the architecture and trace how traffic, routing and access work. Understand before you optimize. #CloudInfrastructure #EmmanueleTech26 Sep 2026 01:39 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwf5nxfsas2rhttps://bsky.app/profile/emmanueletech.com/post/3mwegtlmv3c2uI like asking why before how. How do I configure it? Important. Why does the architecture need it? Just as important. Knowing how helps you build. Understanding why helps you design. #CloudEngineering #EmmanueleTech25 Sep 2026 18:51 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwegtlmv3c2uhttps://bsky.app/profile/emmanueletech.com/post/3mwdqrojhxk2eKnowing the tool and understanding the system are different things. I don’t only want to know how to create infrastructure. I want to understand how the pieces work together and what happens when something fails. #CloudInfrastructure #EmmanueleTech25 Sep 2026 12:16 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwdqrojhxk2ehttps://bsky.app/profile/emmanueletech.com/post/3mwcjc22rfc2rI inherit several servers with public IPs. I wouldn’t immediately change everything. First I’d understand why each one is public and what depends on that access. Secure the environment, but understand it first. #CloudInfrastructure #EmmanueleTech25 Sep 2026 00:29 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwcjc22rfc2rhttps://bsky.app/profile/emmanueletech.com/post/3mwbu5jl7lk2cDoes this resource actually need to be public? It is a simple question, but I think it should be asked more often. Public access should have a reason. #CloudSecurity #CloudNetworking24 Sep 2026 18:11 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwbu5jl7lk2chttps://bsky.app/profile/emmanueletech.com/post/3mwb6jrg6rs2vMorning I prefer thinking about security before deployment. Who needs access? What needs to be public? Which ports are actually required? Security works better when it is part of the design. #CloudSecurity #EmmanueleTech24 Sep 2026 11:44 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mwb6jrg6rs2vhttps://bsky.app/profile/emmanueletech.com/post/3mw7xyeshis2wDashboard is green. Servers are healthy. But users cannot complete an important action. I wouldn’t ignore the users because the metrics look normal. A healthy server doesn’t always mean a healthy service. #CloudOperations #EmmanueleTech24 Sep 2026 00:14 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mw7xyeshis2whttps://bsky.app/profile/emmanueletech.com/post/3mw6r2w3lxk2gA healthy server doesn’t always mean a healthy service. The infrastructure can look normal while users are still having problems. I want to know what the system sees and what the user experiences. #CloudOperations #EmmanueleTech23 Sep 2026 12:38 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mw6r2w3lxk2ghttps://bsky.app/profile/emmanueletech.com/post/3mw5jysjqfs2vTwo servers were configured the same way. One works. The other behaves differently. Before rebuilding anything, I’d compare their configurations and recent changes. Sometimes the problem is configuration drift. #CloudEngineering #EmmanueleTech23 Sep 2026 00:59 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mw5jysjqfs2vhttps://bsky.app/profile/emmanueletech.com/post/3mw4b36owgk2xTwo environments can start identical and slowly become different as manual changes happen over time. Consistency matters. When you know what the configuration should be, troubleshooting becomes much easier. #CloudInfrastructure #EmmanueleTech22 Sep 2026 12:46 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mw4b36owgk2xhttps://bsky.app/profile/emmanueletech.com/post/3mw2xbxdguk2iWhat is the single point of failure? It is one of the questions I like asking when reviewing infrastructure. You don’t make failure impossible. You design so the failures that matter don’t take everything down. #CloudInfrastructure #EmmanueleTech22 Sep 2026 00:18 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mw2xbxdguk2ihttps://bsky.app/profile/emmanueletech.com/post/3mvzw2igp7s2nWhen reviewing infrastructure, I like asking: What happens if this component disappears? Reliability starts with accepting that things can fail and designing around the failures that matter. #CloudInfrastructure #EmmanueleTech21 Sep 2026 14:24 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mvzw2igp7s2nhttps://bsky.app/profile/emmanueletech.com/post/3mvygqhzfic2kThe website loads normally, but submitting data fails. I wouldn’t immediately restart the web server. I’d follow the request and check what happens between the application and its dependencies. Where would you start? #Troubleshooting #EmmanueleTech21 Sep 2026 00:17 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mvygqhzfic2khttps://bsky.app/profile/emmanueletech.com/post/3mvxrnnw27c2cOne question helps me a lot when troubleshooting: What does this system depend on? Once you understand the dependencies, you can test them instead of guessing. #CloudEngineering #EmmanueleTech20 Sep 2026 18:00 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mvxrnnw27c2chttps://bsky.app/profile/emmanueletech.com/post/3mvxeu7piy22nThe component showing the error isn’t always the component causing it. When something fails, I like following the request through its dependencies until I find where it stops. #Troubleshooting #EmmanueleTech20 Sep 2026 14:11 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mvxeu7piy22nhttps://bsky.app/profile/emmanueletech.com/post/3mvvbkkh5lk2vThe last error you see may not be where the problem started. I like building a timeline. What happened first? What changed next? That sequence can tell you more than one error message. #Troubleshooting #EmmanueleTech19 Sep 2026 18:06 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mvvbkkh5lk2vhttps://bsky.app/profile/emmanueletech.com/post/3mvur5l5de22fAn error on the screen rarely tells the whole story. When something fails, I want to know what the system recorded before and during the failure. Logs help turn guessing into investigation. #CloudOperations #EmmanueleTech19 Sep 2026 13:13 +0000at://did:plc:owtkpaxhwgzhatlxtmpdecrn/app.bsky.feed.post/3mvur5l5de22fhttps://bsky.app/profile/emmanueletech.com/post/3mvtg523lvs2uTwo architectures meet the same security, availability and performance requirements. One is much more complex than the other. Would complexity influence your choice?
