After the Cloud Migration: Optimizing Performance and Controlling Costs

According to Gartner, 80% of companies overspend on cloud services by 20-40%, with most of this waste occurring after migration is complete. Meanwhile, Flexera's 2024 State of the Cloud Report shows that optimizing existing cloud use is the top priority for 62% of enterprises—ahead of migration itself.

Why? Because companies are finally realizing that successful migration doesn't equal optimized operations. Your beautifully migrated workloads could be hemorrhaging money through overprovisioned resources, inefficient architectures, and hidden fees. Worse, they might be delivering subpar performance despite all that extra spending. But here's the thing—every one of these problems is fixable.

What Does Cloud Optimization Focus on After Migration?

Cloud optimization after migration isn't about minor adjustments or automated tools. It's basically rebuilding how everything works, except now it's in someone else's data center. You're not just making things work anymore—you're making them work without bleeding money.

Performance Monitoring: Beyond Basic Metrics

Here's what happened to a retail company we worked with. They moved their inventory system to the cloud, hooked it up with Salesforce Manufacturing Cloud, and threw a party. Two weeks later? Their warehouse managers wanted to throw something else—the whole system out the window. Inventory updates that took 30 seconds were now taking 90.

The problem? Nobody told their database queries they weren't in Kansas anymore. Those queries were bouncing between availability zones, through their Boomi cloud integration service, taking the scenic route every single time. Each hop added a few milliseconds. Multiply that by thousands of transactions, and you've got yourself a mess.

So what matters in monitoring? Not just "is it up?" but stuff like:

  1. How long does it actually take to complete a transaction
  2. What's the lag between your hybrid cloud solutions
  3. When are resources actually being used (hint: probably not 24/7)
  4. Are users in different regions having wildly different experiences

Cost Management: Identifying Hidden Expenses

I did a cloud audit recently that made a CFO question his career choices. Here's what we found lurking in their AWS account:

  1. $8,000 monthly on dev environments everyone forgot existed
  2. $12,000 on database instances, basically taking a nap (15% usage)
  3. $3,500 on data transfers nobody knew were happening
  4. $6,000 on backups for projects they killed a year ago

Nearly thirty grand a month. Gone. Poof. And the worst part? This is normal. I see it everywhere.

Why Do Cloud Costs Spiral After Migration?

The Overprovisioning Challenge

Migration is terrifying. Nobody wants to be the person who caused an outage. So what happens? That app needing 16 CPU cores gets 64. You know, just in case the entire internet decides to use it simultaneously. Those extra 48 cores sitting around doing nothing? Two grand a month. Per application. Do the math on that across your whole setup.

Hidden Fees and Unexpected Charges

Cloud providers have more fees than a budget airline. Moving 10TB between regions? That'll be $900, thank you. Is your Salesforce integration making millions of API calls? Cha-ching. NAT gateways processing data? That's gonna cost you. Load balancers running at 3 AM when nobody's working? Still billing. That elastic IP you forgot about? $45 a month, forever.

Resource Sprawl and Zombie Infrastructure

True story: Found 47 "temporary" test environments in a client's account. The oldest one was created by a developer who'd been gone for over a year. Monthly damage: $15,000. This happens because the cloud doesn't run out of space like your server room. There's no limit to how much money you can waste.

How Can You Optimize Costs with Cloud Computing?

Immediate Optimization Strategies

You can cut 20-30% in the first week. I'm not exaggerating. Here's how:

  1. Resource Scheduling: Your dev environments don't need to party all night. Turn them off after hours. Use AWS Instance Scheduler or Azure Automation. Boom—65% savings on non-production stuff.
  2. Right-sizing Resources: That database with 64GB RAM that's using 8GB? Yeah, that one. Shrink it. We had a client save $8,640 per year just going from m5.4xlarge to m5.xlarge. They had 23 of these. You do the math.
  3. Eliminating Waste: Delete the junk. Unattached volumes, old snapshots, AMIs from 2019—it's all costing money. Two hours of cleanup usually saves thousands monthly.

Strategic Optimization Approaches

Now for the bigger wins—another 25-35% savings:

  1. Reserved Instances: If you know you'll need something for a year, why pay month-to-month? It's like paying hotel rates when you could sign a lease. One year saves 40%. Three years? 60% off.
  2. Spot Instances: Perfect for stuff that can handle interruptions. Dev environments save 70%. Batch jobs save 80%. Just make sure your apps can handle getting kicked off occasionally.
  3. Storage Optimization: Old logs don't need premium storage. Set up lifecycle policies. Move cold data to cheaper tiers. One SaaS company went from $180K to $108K monthly just doing this. That's almost a million bucks a year.

Where Do Performance Issues Hide?

Latency Accumulation

Your app makes 50 API calls to load a page. Each one adds 20ms. Do the math—that's a full second of waiting. Users feel anything over 200ms. At three seconds, they're gone. And when you're dealing with Salesforce Manufacturing Cloud or juggling hybrid cloud solutions? Those delays stack up fast.

Database Architecture Mismatches

That beautiful JOIN query your DBA wrote five years ago? It assumes everything's in the same room. In the cloud, your tables might be in different zip codes. Each lookup now has travel time. Get a hundred users hitting it at once? Congratulations, you've created a traffic jam.

Cold Start Challenges

Serverless is great until it's not. User clicks the button. Function hasn't run in 20 minutes. Cold start kicks in. Three to five seconds later, maybe it responds. Meanwhile, your user has rage-clicked seventeen times. Now you've got seventeen functions spinning up. Chaos.

Which Optimization Strategies Work Best?

For AI and Machine Learning Workloads

GPUs are expensive. Like, really expensive. Three to four bucks an hour, which is expensive. One startup was burning $45K monthly, mostly on GPUs sitting idle between training runs.

Fix? Use spot instances for training (80% cheaper). Set up automatic shutdowns. Pick the right GPU for the job—not everything needs a V100. Result: $12K monthly instead of $45K. Same work, way less money.

For Manufacturing and ERP Systems

Salesforce Cloud ERP manufacturing is powerful but hungry. Every API call costs money. Every custom field slows things down. Solution? Use Bulk API for big operations. Index your custom objects properly. Write smarter queries. Use Platform Events instead of constant polling.

One manufacturer did this and got 4x better performance while cutting API costs by 60%. That's what we're talking about.

The Role of Professional Services

Look, sometimes you need help. When should you call in an IT maintenance services company for cloud infrastructure? When your bill's over $50K monthly. When optimization becomes someone's full-time job. When you realize you're in over your head.

At AD Infosystem, we've done this dance hundreds of times. We typically cut costs by 35% while making things run 50% faster. Not because we're wizards—we just know where to look.

Summary

The numbers don't lie—80% of companies overspend on cloud by 20-40% after migration. Without active management, your cloud environment becomes an expensive mess, performing worse than your old setup.

Focus on four areas: performance monitoring, cost management, security, and integration. Costs explode from overprovisioning, zombie resources, and hidden fees.

Quick wins: Turn off unused resources and right-size the rest (20-30% savings). Strategic moves: Reserved instances and storage optimization (another 25-35%).

Different workloads need different approaches—AI needs spot instances, manufacturing needs efficient Salesforce integration. Companies that optimize see costs drop 50% while performance improves 50%. Those who don't keep overpaying for poor service.

Frequently Asked Questions (FAQs)

Yesterday would've been good. Today works too. Seriously, the first month after go-live is when you'll spot the expensive mistakes. Every day you wait is money down the drain.

First 90 days? 20-40% is typical. Long term? I've seen 60% cuts. Had one client go from $2.1M to $950K annually. Your mileage may vary depending on how much waste you're carrying.

API calls will eat you alive. Use bulk operations. Archive old data. Get your team proper Salesforce Manufacturing Cloud training. One badly configured workflow can cost thousands monthly.

Usually 3-5x in the first year. Most save enough in 3-4 months to cover a whole year of consulting. After that, it's gravy.
