About the Client
Our client is a rapidly growing Israeli B2B SaaS platform providing analytics and data visualization tools to enterprise customers across Europe and North America. With annual recurring revenue exceeding $10M and ambitious growth targets, they needed enterprise-grade infrastructure reliability and scalability. Their engineering team of 25 developers was spending more time fighting infrastructure fires than building product features. As a compliance-focused business serving Fortune 500 clients, they needed robust security controls and audit trails to achieve SOC 2 certification.
Challenges
Skyrocketing AWS Costs
Monthly AWS bill had grown from $5K to $15K in 6 months without corresponding growth in revenue or users. No cost visibility, over-provisioned resources, and inefficient architecture.
Pain Points:
• No cost attribution per customer or feature
• Production databases running 24/7 on oversized instances
• Development environments never shut down
• No Reserved Instances or Savings Plans
• Unoptimized data transfer and storage costs
Manual Infrastructure Management
All infrastructure changes were done manually through AWS Console. No version control, no reproducibility, and significant drift between environments.
Pain Points:
• Production deployments took 2-3 days with manual checklists
• Environment configuration drift caused mysterious bugs
• Onboarding new developers took weeks
• Disaster recovery was untested and undocumented
• Compliance audits revealed gaps in change tracking
Frequent Production Incidents
Weekly production incidents and outages were damaging customer trust and SLA compliance. No observability, reactive firefighting, and weekend escalations.
Pain Points:
• Average 2.5% monthly downtime (97.5% uptime)
• Mean Time To Recovery (MTTR) of 4+ hours
• No proactive monitoring or alerting
• On-call engineers burned out from frequent pages
• Customers complaining about reliability
Security & Compliance Gaps
Preparing for SOC 2 audit revealed significant security and compliance gaps. Manual processes, no audit trails, and inconsistent security controls.
Pain Points:
• Secrets stored in plaintext in repositories
• No centralized IAM management
• Incomplete logging and audit trails
• No automated vulnerability scanning
• Manual security patching falling behind

CI/CD & Automation
Built automated deployment pipelines with GitHub Actions, implementing GitOps workflows for infrastructure and application deployments. Established automated testing, security scanning, and progressive delivery.
Infrastructure Pipeline
Terraform changes go through automated planning, validation, security scanning (Checkov), cost estimation (Infracost), and peer review before apply. Automatic rollback on failures.
Application Pipeline
Automated build, test, security scan (Snyk, Trivy), container image creation, and deployment to Kubernetes. Blue/green deployments with automated smoke tests and rollback.
GitOps Workflow
All deployments declared in Git and synced to Kubernetes via ArgoCD. Complete audit trail, easy rollbacks, and separation of build/deploy concerns.
Observability, Security & Governance
Implemented comprehensive monitoring, logging, and tracing with Datadog. Built automated alerting with PagerDuty integration. Established security scanning, secrets management, and compliance automation.
Monitoring & Alerting
Unified observability platform with metrics, logs, and traces. Custom dashboards for application health, infrastructure utilization, and business KPIs. Smart alerting with reduced noise.
Security & Secrets Management
Implemented HashiCorp Vault for secrets management with dynamic database credentials and automated rotation. Container image scanning, dependency scanning, and automated security patching.
Logging & Audit Trails
Centralized logging to Datadog with CloudTrail for AWS API calls, Kubernetes audit logs, and application logs. Automated compliance reports and security event monitoring.
Architecture Overview
The architecture consists of a multi-account AWS organization with production, staging, and development accounts. Applications run on Amazon EKS clusters with auto-scaling node groups across 3 availability zones. RDS PostgreSQL provides the database layer with automated backups and read replicas. CloudFront CDN accelerates content delivery. All infrastructure is defined in Terraform and deployed via GitHub Actions with ArgoCD managing Kubernetes deployments. Datadog provides unified observability, while Vault manages secrets and credentials. Transit Gateway connects VPCs, and Site-to-Site VPN enables secure developer access.

Container scanningFAQ: AWS CloudOps & IaC for SaaS / Enterprise Software
Companies often ask us similar questions before we start a project, so we've included short answers below.
AWS CloudOps combines cloud operations management, automation, and best practices to run reliable, secure, and cost-efficient AWS infrastructure. For SaaS companies, it means reduced operational overhead, faster deployments, better uptime, and predictable costs. HostingX provides 24/7 managed CloudOps services specifically for Israeli and EMEA SaaS businesses.
Implementation timeline depends on infrastructure complexity and organization readiness. Most projects follow this pattern: 2 weeks for assessment and design, 6-12 weeks for implementation (infrastructure migration, IaC, CI/CD, observability), and 2-4 weeks for testing and knowledge transfer. We often deliver quick wins (cost savings, monitoring) in the first month while building toward the complete solution.
Absolutely. We specialize in incremental migrations and brownfield transformations. We assess your current AWS environment, identify improvement opportunities, and create a phased migration plan that minimizes disruption. We can work with your existing tools (Jenkins, GitLab, Prometheus, etc.) or recommend better alternatives. The goal is pragmatic improvement, not a disruptive "rip and replace."
Minimal preparation is needed to get started. We typically need: (1) AWS account access for assessment, (2) overview of your current architecture and pain points, (3) access to key stakeholders (CTO, DevOps lead, engineers), and (4) clarity on business goals (cost reduction, reliability, compliance, etc.). We handle the rest – discovery, design, implementation, and knowledge transfer.
Cost savings vary by starting point, but most clients see 30-50% reduction within 3-6 months. Common savings sources include: rightsizing over-provisioned resources (20-30%), implementing Reserved Instances and Savings Plans (40-60% on baseline compute), optimizing storage with lifecycle policies (30-50%), eliminating idle resources (varies), and architecting for efficiency (10-30%). We provide detailed cost analysis during the assessment phase.
Yes! HostingX offers 24/7 managed CloudOps services including proactive monitoring, incident response, performance optimization, cost management, security updates, and continuous improvement. Many clients start with implementation and transition to ongoing managed services. We become an extension of your team, handling infrastructure operations so your engineers can focus on product development.
