Cloud Architecture Review Powerpoint Presentation Slides

Honestly, just focus on three things: scalability, reliability, and security. Don't just buy bigger servers when you hit limits - scale horizontally instead, it's way cheaper. Build everything expecting it'll break because cloud stuff always does. Redundancy is your friend here. Security needs to be built in from the start, not slapped on later when you realize you screwed up. Oh, and keep your services loosely coupled so you can actually deploy without breaking everything else. Start with getting one service really solid before you go crazy with microservices - trust me on that one.

So microservices are basically about splitting your app into smaller, independent pieces instead of having one giant codebase. Each piece does its own thing and you can deploy them separately - super helpful when stuff breaks. You'll need containers and API gateways to make everything talk to each other properly. Honestly, the orchestration gets pretty messy, but the flexibility is worth it IMO. My advice? Don't go crazy right away. Try splitting into maybe 2-3 services first to see how it feels before you go full microservices mode.

Yeah, the big win is avoiding vendor lock-in - you can use AWS for compute, Google for AI stuff, Azure for enterprise things. Better redundancy too, and you can pit them against each other on pricing. But man, it gets messy quick. Now you're juggling multiple billing systems, different security setups, various toolsets. Your team needs to know all these platforms, which costs a fortune and good luck finding people. Oh, and connecting everything between clouds? Total pain. I'd say start small - maybe just use one for backup while keeping your main stuff somewhere else.

So basically, IaaS means you're handling everything - networking, storage, all that server stuff. It's like building from the ground up. PaaS takes care of most of that headache for you, so you can focus on your actual app instead of managing infrastructure. With SaaS you're just plugging into what someone else already built. Honestly, I'd say pick based on how much time you have and what your team actually knows. If you need to ship something quickly, don't torture yourself with IaaS - that's way too much work just to get features out the door.

Zero-trust is your best friend here - don't trust anything by default. Encrypt literally everything, both stored data and stuff moving around. MFA on every single account, no exceptions (I got burned skipping this once, ugh). Set up IAM roles but keep permissions super tight - only give people what they actually need. Oh and audit those permissions regularly because they get messy fast. Turn on logging for all your services, patch stuff promptly, and segment your network so critical systems stay isolated. Honestly though? Start with a security assessment first - figure out your biggest vulnerabilities and tackle those.

Right-size your stuff first - everyone goes way overboard with provisioning. Auto-scaling helps match actual demand, and reserved instances are solid for predictable workloads. Spot instances work great for anything non-critical. Storage tiering saves a ton - just auto-move old data to cold storage. But honestly? The easiest win is turning off dev/test environments when they're not being used. It's ridiculous how much that alone saves. Set up cost alerts so you don't get slammed with surprise bills. Oh, and audit regularly to kill those zombie instances that are just sitting there burning cash for no reason.

Dude, containers are a total game changer. They package your app with everything it needs, so it runs the same everywhere - no more "works on my machine" BS. Way lighter than VMs too. Docker's probably your best starting point if you haven't messed with it yet. The coolest part? You can scale each service separately instead of your whole monolith. Deployments get way faster. Your DevOps people will actually thank you for once lol. Microservices without containers is honestly just painful at this point.

Microservices with containers are honestly where it's at - breaks everything into manageable chunks that scale independently. Auto-scaling groups handle the heavy lifting so your infrastructure adapts automatically. Kubernetes has a brutal learning curve but pays off big time once you get it. Build stateless services when you can. Managed stuff like RDS and Lambda cuts down on all the ops headaches you'd otherwise deal with. Load balancing is crucial too. Oh, and multi-region deployments if you want real bulletproof setup. I'd start with migrating just one service first, see how it goes, then move the rest piece by piece.

Honestly, start with figuring out what data you're actually dealing with - like what's sensitive vs just regular stuff. That's gonna drive everything else. Where does it live physically? Some compliance rules are weirdly picky about that. Back it up across regions, encrypt everything moving around and sitting still. Access controls are huge though - the cloud makes it SO easy to accidentally leave doors wide open. Get your permissions locked down right away, not later when you realize someone can see everything. Oh and map out how your data flows first, then build around that. Way easier than trying to bolt security on afterward.

Oh man, serverless is wild - you basically stop worrying about servers altogether and just write functions that fire when stuff happens. Your app automatically scales up when it's busy, scales down when it's not. I love that you only pay for what you actually use instead of some server just sitting there burning money. You end up breaking everything into these smaller functions rather than one giant app, which honestly makes updates way easier since you can change one piece without breaking everything else. Takes some getting used to but it's pretty freeing once you wrap your head around it.

Start with whatever your cloud provider gives you - CloudWatch for AWS, Azure Monitor, or Google's Stackdriver. Prometheus is great for collecting metrics, and honestly Grafana makes the prettiest dashboards (I kind of geek out over those). Terraform's become the go-to for infrastructure as code, which you'll definitely want. Oh, and don't skip logging - ELK stack or Splunk will save your butt when things break. I'd say begin with the native cloud tools first. You can always add the fancy stuff later when your setup gets messier.

So cloud-native stuff gets built specifically for the cloud from scratch. Traditional architecture? That's more like dragging your old office setup into a new building - it works but feels clunky. Microservices and containers are huge with cloud-native because they scale automatically when traffic goes crazy. Traditional apps are usually these massive monoliths that are a pain to update. Oh, and cloud-native assumes everything's gonna break eventually, so it builds that resilience in upfront. Honestly, if you're starting something new, just go cloud-native. You'll save yourself so many headaches later when you need to grow fast.

Look, compliance isn't something you tack on later - it shapes your entire cloud setup from the start. Data residency rules decide where your stuff can live. Encryption and access controls? Non-negotiable. GDPR, HIPAA, SOX all have their own quirks but they'll all mess with your architecture decisions if you ignore them. Your cloud provider's certs help (thank god), but you're still on the hook for configuring everything right. Honestly, just map out your regulatory requirements against your components early - saves you from wanting to burn it all down later.

Start with Infrastructure as Code right away - Terraform or CloudFormation will save you so much headache later. Most teams screw this up by bolting on CI/CD afterward instead of building it into the architecture from the beginning. You'll want centralized logging and monitoring baked in too. Containers and microservices work great here, but honestly don't go overboard if your app doesn't need it. Oh, and treat everything like code instead of clicking around in consoles. Version control is your friend. The whole point is making deployments boring and predictable.

First things first - spread your stuff across multiple zones and regions so you're not screwed if one area goes down. Automated backups are clutch, but seriously test them regularly. I've watched so many people discover their backups were garbage during an actual emergency. Multi-cloud can help but honestly gets messy to manage. Set up monitoring with automatic failover, and use infrastructure as code so you can rebuild fast. Oh, and actually practice your disaster recovery - like quarterly drills. Nobody wants to figure out their plan doesn't work when everything's on fire.
