AWS EC2 Support
AWS EC2 support, troubleshooting and optimization.
Amazon EC2 runs a large share of production workloads on AWS. Most outages and surprise bills trace back to a short list of causes: throttled or undersized instances, full disks, broken networking and unmanaged scaling.
Common EC2 problems we fix
The Amazon EC2 issues our engineers see most often, and how we resolve them.
EC2 instance high CPU or slow performance
Burstable T-family instances are throttled to their baseline when CPU credits run out, and undersized instance families or memory pressure cause the same symptoms. We read CPUCreditBalance, utilization and steal time in CloudWatch, profile the busy process, then right-size, enable unlimited mode or move to a fixed-performance family such as M or C.
Cannot SSH or RDP into an EC2 instance
The usual causes are security group or network ACL rules, a missing public IP or internet gateway route, the wrong key pair or username, a full disk, or a failed sshd. We get access through Session Manager, EC2 Instance Connect or by attaching the root volume to a rescue instance, then fix the cause.
EC2 status check failed or instance will not start
A failed system check points at the underlying host, which a stop and start usually moves. A failed instance check points at the operating system: a broken fstab, kernel problem or full root volume. We use console output and screenshots, then repair the volume from a rescue instance.
Unexpectedly high EC2 bill
Common drivers are idle or oversized instances, on-demand pricing where Savings Plans fit, unattached EBS volumes and Elastic IPs, and data transfer or NAT gateway charges. We right-size, apply Savings Plans or Reserved Instances, move suitable workloads to Graviton and use Spot for stateless jobs.
Auto Scaling not scaling or flapping
Wrong metrics, short cooldowns, a health check grace period that is too small, or launch templates pointing at unavailable capacity make scaling unreliable. We switch to target tracking, fix warm-up and health checks, and diversify instance types and subnets.
How We Help With EC2
Senior AWS engineers who explain what they change and why.
What we do
- Incident triage and root-cause analysis
- Right-sizing and Graviton migration
- Auto Scaling, load balancer and AMI pipeline setup
- Patching, backup and monitoring baseline
How it works
- Tell us what is wrong or what you want to improve
- We review with read-only access first
- We fix, explain and document the change
- We hand off with monitoring so it stays fixed
Specialized EC2 support
Deep-dive help for specific EC2 tasks.
AWS EC2 right-sizing without the riskRight-size AWS EC2 instances with real metrics. TwinTix uses CloudWatch, Compute Optimizer and testing to cut cost without hurting performance or availability.
AWS Savings Plans vs Reserved Instances: what to buyChoose between AWS Savings Plans and Reserved Instances. TwinTix sizes commitments from real usage so you save without over-committing.
EC2 status check failed: find the cause and recover the instanceEC2 instance status check failed or impaired? TwinTix finds whether AWS or your OS is at fault, recovers the instance and sets up automatic recovery.
EC2 SSH connection timed out: trace the path and restore accessCannot SSH or RDP into your EC2 instance? TwinTix traces the network path, security groups, NACLs and OS firewall to restore access safely.
EC2 T3 and T4g CPU credit throttling: diagnose and fixSlow EC2 T3, T3a or T4g instance? TwinTix checks CPU credit balance, unlimited mode and surplus charges, then fixes the sizing or instance family.
EC2 Spot interruption handling: run on Spot without outagesRun EC2 Spot safely. TwinTix designs for the two-minute interruption notice with diversified pools, capacity rebalancing and graceful draining.
EC2 Graviton migration: move to arm64 with proof it worksMove EC2 workloads to Graviton instances safely. TwinTix checks ARM compatibility, rebuilds images, benchmarks and rolls out with rollback in place.
EC2 AMI pipeline and patching with Image Builder and Patch ManagerBuild golden AMIs with EC2 Image Builder and patch fleets with Systems Manager Patch Manager. TwinTix sets up the pipeline, baselines and rollout.
Frequently Asked Questions
How do I fix an EC2 instance that is unreachable?
Check the instance and system status checks, the security group and network ACL, the route table and the instance's own firewall. If SSH or RDP still fails, Session Manager or a rescue instance can reach the disk. We can work through this with you or take over the incident.
Can you reduce EC2 costs without downtime?
Most savings (Savings Plans, removing idle resources, gp2 to gp3) need no downtime. Changing instance types usually needs a short restart, which we schedule in a maintenance window.
Do you support both Linux and Windows instances?
Yes. We work with Amazon Linux, Ubuntu, other Linux distributions and Windows Server on EC2.
