How to Present Cloud Migration Success Using Specific Performance Improvement Figures on CV
Hiring managers and applicant tracking systems (ATS) love hard numbers. When you migrated a legacy system to the cloud, the story isn’t just "we moved to AWS"—it’s "we cut costs by 32% and improved page load speed by 45%". This guide walks you through turning those performance improvement figures into resume gold, complete with checklists, examples, and FAQs.
Why Numbers Matter on a CV
- ATS friendliness – Keywords like "cost reduction" and "performance improvement" are parsed by ATS algorithms. Adding the exact percentage or dollar amount makes the match stronger.
- Credibility – Recruiters skim dozens of resumes. A concrete figure instantly validates your claim.
- Differentiation – Most candidates say "led cloud migration". Few can back it up with "reduced latency by 2.3 seconds".

Step‑by‑Step Guide: From Raw Data to Resume Bullet
1️⃣ Gather the source data
| Metric | Before Migration | After Migration | Improvement |
|---|---|---|---|
| Monthly cloud spend | $120,000 | $78,000 | 35% cost reduction |
| Average page load time | 4.8 s | 2.6 s | 46% faster |
| Deployment frequency | 1 per month | 4 per week | 300% increase |
| Incident MTTR (Mean Time to Recovery) | 6 hrs | 1.2 hrs | 80% faster recovery |
2️⃣ Translate raw numbers into impact statements
- Cost reduction: "Reduced monthly cloud spend by 35% ($42K) through rightsizing EC2 instances and implementing auto‑scaling."
- Performance boost: "Improved page load speed by 46% (2.2 s), raising user satisfaction scores from 78% to 92%."
- Delivery speed: "Increased deployment frequency from 1 per month to 4 per week, accelerating time‑to‑market for new features."
- Reliability: "Cut Mean Time to Recovery by 80%, bringing incident resolution down to 1.2 hrs."
3️⃣ Choose the right resume section
| Section | When to use |
|---|---|
| Professional Experience | Core cloud‑migration role, senior‑level positions |
| Projects (if you have a dedicated projects section) | Freelance or contract migrations |
| Achievements (bullet‑point list) | One‑liner impact statements |
4️⃣ Write the bullet using the STAR (Situation, Task, Action, Result) framework
Example: *"Led a cross‑functional team to migrate a legacy monolith to AWS, implementing automated CI/CD pipelines. Result: 35% cost reduction ($42K/month) and 46% faster page loads, boosting customer satisfaction from 78% to 92%."
5️⃣ Optimize for ATS keywords
- Cloud migration, AWS, Azure, GCP
- Cost optimization, performance tuning, latency reduction
- CI/CD, automation, DevOps, scalability
- KPI, SLA, MTTR, uptime
Checklist: Does Your Cloud Migration Bullet Pass the Test?
- Specific metric (percentage, dollar amount, time saved)
- Baseline (what it was before)
- Result (what it is after)
- Context (technology stack, team size, business impact)
- ATS keywords embedded naturally
- Action verb at the start (Reduced, Improved, Accelerated, Optimized)
If any box is unchecked, revisit step 2‑4.
Do’s and Don’ts
| Do | Don't |
|---|---|
| Do quantify every claim. | Don’t use vague terms like "significant" or "substantial" without numbers. |
| Do keep the bullet under 2 lines for readability. | Don’t overload a single bullet with multiple unrelated metrics. |
| Do align the metric with business outcomes (cost, revenue, user experience). | Don’t mention internal tool names that recruiters won’t recognize. |
| Do use active voice and strong verbs. | Don’t write in passive voice ("The migration was completed…"). |
Real‑World Example: From Draft to Polished Bullet
Draft: "Worked on cloud migration and improved performance."
Polished: "Directed a 6‑person team to migrate a legacy e‑commerce platform to AWS, achieving 46% faster page loads (2.2 s) and 35% monthly cost reduction ($42K), which lifted conversion rates by 12%.
Notice the inclusion of:
- Action verb – Directed
- Team size – 6‑person team
- Technology – AWS
- Specific figures – 46%, 2.2 s, 35%, $42K
- Business impact – 12% lift in conversion rates

Q3: Should I round percentages? A: Yes. Round to the nearest whole number unless the decimal is critical (e.g., 2.6 s vs 2.60 s).
Q4: My project was a team effort. How do I claim credit? A: Use collaborative verbs: "Co‑led", "Partnered with", or "Collaborated with a 5‑member team to achieve…".
