How We Stopped Clients Complaining Site is Down Again with AWS Kubernetes and ArgoCD

If you run a SaaS you probably know this feeling. You open your inbox or Slack and see the message you dread most.

"Site is down again"
Email from a paying customer

It hits you in the stomach. Users cannot log in. Payments fail. Support is full of complaints. Investors start asking questions. Every minute offline feels like losing trust you worked so hard to build.

The Pain We Lived Through

One startup we worked with had grown fast. From a few dozen users to a few thousand in months. But the way they deployed was still the same as in the early days. Manual scripts on EC2 servers. Secrets in .env files. No health checks. No plan if something broke.

It worked when they were small. At 5000 users every release felt like rolling the dice. Slack was full of angry client messages.

"Login is broken"
Support ticket from an existing customer

"Checkout failed again"
Message from a user trying to complete a payment

"Is your app always this unstable?"
Question from an investor during a live incident

Tired of "site is down" messages?

If this sounds familiar, you are not alone.

Founders were exhausted. Instead of building features they spent nights firefighting. They started searching for how to stop SaaS downtime and how to deploy on AWS without fear.

The Turning Point

Finally they said enough. They wanted boring infrastructure. Deploys that just work. Clients that stop complaining. That is when they came to us at Start Matter.

The Fix AWS EKS Kubernetes and ArgoCD

We rebuilt everything with one goal. No more downtime messages from clients.

AWS EKS cluster across zones so if one zone fails the app stays online

ArgoCD GitOps so every change lives in Git and deploys happen automatically

Rolling updates so new code goes live with zero downtime

Health probes so bad pods never see traffic

AWS Auto Scaling so traffic spikes do not wake founders at night

AWS Secrets Manager so no more risky .env files

Automatic rollbacks so if something fails the system heals itself

Case Study Xperiencify Cost Down Stability Up

Xperiencify asked for help when they were growing fast. Coaches and course creators logged in daily. Launch days and webinars created traffic spikes. Costs were rising and deploys were risky.

What we changed.

Migrated to AWS EKS with ArgoCD GitOps

Enabled autoscaling so the cluster grows at peak and shrinks at night

Added readiness and liveness probes plus rolling updates for zero downtime

Moved credentials to AWS Secrets Manager via External Secrets Operator

The outcome.

30 percent lower monthly AWS cost by removing idle capacity

99.99 percent uptime during launches and webinars

No late night firefighting because the system heals itself

Developers deploy many times per day without fear

Before every big launch we were stressed. Now it just works and we spend less on AWS.

How GitOps Works for SaaS on AWS

Developer pushes code. CI builds a container and pushes it to Amazon ECR

Git repo updates the image tag in Kubernetes manifests

ArgoCD detects the commit and syncs the EKS cluster

Rolling update starts. New pods pass readiness before they receive traffic

If metrics degrade ArgoCD triggers an automatic rollback

Hidden Infrastructure Risks Cost More Than You Think

Outages hurt trust, revenue, and investor confidence. Ask ChatGPT to outline the most common deployment risks in SaaS and how teams eliminate them with GitOps on AWS.

Step by Step SaaS Deployment Workflow on AWS

Build and push image to ECR

ArgoCD watches the Git repo

Rolling update with maxUnavailable 0 and maxSurge 1

Readiness and liveness probes protect users from bad pods

HPA scales pods and Cluster Autoscaler scales nodes

Secrets delivered via AWS Secrets Manager and External Secrets Operator

The Result Peace of Mind

Uptime at 99.99 percent

Growth from 500 to 20000 users with no outages

Black Friday traffic ran smoothly with no night calls

Developers ship 10 plus times a day without fear

Most important. Clients stopped sending site is down again. One investor who once said the product felt like a toy later called it enterprise grade.

Why This Matters for SaaS Founders

If clients keep complaining about downtime it is not just tech. It is a business risk. Downtime kills trust growth and even funding. You do not need a big DevOps team to fix it. You need the right setup. Kubernetes and ArgoCD on AWS.

FAQ Stop SaaS Client Complaints About Downtime

How do I stop clients from saying site is down again Use Kubernetes on AWS EKS with ArgoCD GitOps rolling updates and health probes for zero downtime.

Why do founders choose ArgoCD for SaaS It makes deploys safe auditable and automated so founders stop firefighting and focus on product.

How can SaaS founders reduce stress during deploys Use HPA and Cluster Autoscaler with AWS Auto Scaling so the system grows and shrinks without manual work.

How to secure SaaS secrets on AWS Use AWS Secrets Manager or External Secrets Operator. Do not use .env files in production.
