# Cloud Server Operations and Management Service

**URL:** https://securesys.com.tr/en/services/cloud-server-operations-management-service

A significant part of corporate applications now runs on cloud infrastructure rather than physical servers. But moving a server into a cloud environment does not mean that system automatically becomes secure, high-performing, redundant and uninterrupted.

Servers running in the cloud also need regular monitoring, operating system updates, performance tracking, security setting reviews, verification of backup processes and correct capacity planning.

**SecureSys Cloud Server Operations and Management Services** provide end-to-end support for the deployment, management, monitoring, maintenance, security and operational processes of Windows and Linux servers running in an organization's public cloud, private cloud and hybrid cloud environments.

Within the service, the aim is not simply to keep cloud servers running, but to evaluate them continuously in terms of performance, availability, security, cost, backup and business continuity.

SecureSys builds its cloud server operations approach on an integrated management model that handles the;

**Cloud + System + Network + Security + Backup + Monitoring + SOC**

components together.

### What Is a Cloud Server?

A cloud server is a server resource that runs on virtualized or cloud-native infrastructure without being directly tied to physical server hardware.

Cloud servers can be scaled quickly according to need in terms of;

- processor,
- RAM,
- disk,
- network,
- IP address,
- operating system,
- security policies

and similar resources.

Corporate applications;

- web applications,
- ERP,
- CRM,
- databases,
- Active Directory services,
- application servers,
- file services,
- API systems,
- test and development environments

can all be run on cloud servers.

### What Is a Cloud Server Operations Service?

A Cloud Server Operations Service covers the management of the daily operations of servers running in a cloud environment by expert teams.

Within the SecureSys Cloud Server Operations Service;

- server deployment,
- operating system management,
- user and access management,
- patch management,
- disk and capacity tracking,
- performance monitoring,
- log management,
- backup verification,
- security controls,
- troubleshooting,
- incident management

processes can be carried out.

This model can reduce an organization's need to keep a cloud system administrator on staff continuously, and help existing IT teams focus on more strategic work.

### Managed Cloud Server Service

**Managed Cloud Server** is running the deployment, operation, maintenance and monitoring processes of cloud servers under a managed service model.

Within the SecureSys Managed Cloud Server service;

- Windows Server management,
- Linux Server management,
- monitoring,
- patching,
- hardening,
- backup,
- capacity management,
- network access,
- firewall policies,
- incident response

and similar processes can be managed centrally.

Depending on the organization's requirements, the service can be delivered periodically, within business hours, or with a 7x24 monitoring model.

### Public Cloud Server Management

In public cloud infrastructure, servers run on shared provider infrastructure but use virtual resources allocated to the organization.

In public cloud server management, SecureSys can evaluate components such as;

- compute resources,
- virtual machine,
- disk,
- network,
- security group,
- backup,
- monitoring,
- access management

together.

The aim is not simply for the server to run, but for the services the cloud provider offers to be used securely and correctly.

### Private Cloud Server Management

Private Cloud refers to systems running on private cloud infrastructure dedicated to the organization.

These structures can be located in the organization's own data center or in a service provider's data center.

Within SecureSys Private Cloud management, the;

- virtualization infrastructure,
- virtual machine,
- storage,
- network,
- backup,
- monitoring,
- access management

processes can be managed.

### Hybrid Cloud Management

Many organizations do not move all their systems entirely to the cloud.

Some critical systems remain in the organization's own data center while other applications run in the cloud.

This structure is called **Hybrid Cloud**.

In hybrid infrastructures, SecureSys handles the;

- on-premise network,
- cloud network,
- VPN,
- identity,
- backup,
- monitoring,
- security

integrations together.

### Multi-Cloud Management

Some organizations may use more than one cloud provider at the same time.

While an application runs on one cloud platform, backup or other services may sit with another provider.

In multi-cloud environments, SecureSys can support standardizing the;

- central visibility,
- standard security policies,
- access management,
- monitoring,
- backup,
- cost tracking

processes.

### Windows Cloud Server Management

Windows Server systems running in the cloud require regular management just as physical servers do.

Within SecureSys Windows Cloud Server services, the;

- Windows Server deployment,
- patch management,
- Active Directory,
- DNS,
- DHCP,
- IIS,
- RDP security,
- event log management,
- backup

processes can be carried out.

### Linux Cloud Server Management

Linux systems are widely used in web, application, database and container infrastructure.

In SecureSys Linux Cloud Server management, the;

- user and group management,
- SSH security,
- package updates,
- service management,
- disk usage,
- log analysis,
- firewall,
- monitoring,
- backup

operations can be carried out.

### Cloud Server Deployment Service

A new cloud server deployment should not be considered complete once the operating system has been created.

Before deployment, the;

- application requirement,
- CPU,
- RAM,
- disk,
- network,
- operating system,
- security,
- backup,
- growth requirement

should be evaluated.

SecureSys performs appropriate sizing so the cloud server is prepared for the production environment.

### Cloud Server Sizing

An incorrectly sized cloud server either creates performance problems or generates unnecessary cost.

In SecureSys Cloud Server Sizing work, the;

- CPU usage,
- RAM requirement,
- disk capacity,
- IOPS,
- network traffic,
- number of users,
- application load

can be evaluated.

The aim is to avoid allocating resources below or far above the actual need.

### Right-Sizing

One of the important advantages of cloud environments is that resources can be increased or reduced as needed.

With a right-sizing approach, SecureSys analyzes current server usage figures and can produce optimization recommendations for;

- excess CPU,
- unused RAM,
- unnecessary disk capacity,
- underused systems

and similar cases.

### Cloud Server Performance Management

The performance of cloud servers should not be assessed by looking at CPU usage alone.

In SecureSys performance analysis, metrics such as;

- CPU,
- RAM,
- disk latency,
- IOPS,
- network throughput,
- load average,
- application response time

can be evaluated together.

### 7x24 Cloud Server Monitoring

A service outage on critical cloud systems can affect an organization's operations directly.

Depending on the service scope, SecureSys can bring cloud servers into a 7x24 monitoring system.

The main metrics that can be monitored;

- server availability,
- CPU,
- RAM,
- disk,
- network,
- critical services,
- process,
- ports,
- backup status

can be configured in this way.

### Proactive Monitoring

One of the core aims in cloud operations services is to detect problems before users notice them.

For example, alarms can be raised at defined thresholds rather than waiting for disk usage to reach 100%.

Likewise;

- rising CPU usage,
- falling disk capacity,
- a stopped service,
- an unreachable server,
- a failed backup

and similar conditions can be tracked proactively.

### Cloud Server Health Check

Cloud servers that have been running for a long time can grow in an uncontrolled way over time or weaken from a security perspective.

Within the SecureSys **Cloud Server Health Check**, the;

- operating system,
- patch level,
- CPU and RAM,
- disk,
- network,
- users,
- services,
- firewall,
- backup,
- logging,
- security settings

can be examined.

Improvement recommendations can be produced at the end of the work.

### Cloud Server Hardening

Exposing cloud servers to the internet with default configurations can create serious security risks.

In SecureSys Cloud Server Hardening work, the;

- disabling of unnecessary services,
- restriction of administrator access,
- SSH/RDP security,
- firewall,
- MFA,
- patch management,
- logging,
- secure protocols

can be evaluated.

### RDP Security

Leaving the RDP port of Windows cloud servers open directly to the internet is one of the significant attack risks.

For secure access, SecureSys can evaluate options such as;

- VPN,
- Bastion Host,
- Jump Server,
- IP restriction,
- MFA,
- PAM

and similar controls.

### SSH Security

SSH access on Linux cloud servers must be configured securely.

SecureSys can apply;

- root login restriction,
- SSH key authentication,
- IP restriction,
- MFA,
- port access control,
- fail2ban-style protections

and similar measures.

### Cloud Firewall Management

In cloud environments, not only the operating system firewall but also provider-level network security controls can be used.

SecureSys can support the management of;

- Security Group,
- Network ACL,
- Cloud Firewall,
- inbound rule,
- outbound rule

policies.

### Network Access with Least Privilege

Making cloud servers reachable from the entire internet is not recommended.

In access policies, SecureSys applies a minimum access approach on a;

**Source → Destination → Port → Protocol**

basis wherever possible.

This helps reduce the attack surface.

### Cloud Network Segmentation

Having different systems in the same network segment in cloud environments can increase security risk.

SecureSys can create security segments such as;

- Web Tier,
- Application Tier,
- Database Tier,
- Management Tier,
- Backup Tier

and similar layers.

Example architecture:

**Internet → Cloud Firewall → Web Tier → Application Tier → Database Tier**

This approach helps limit an attacker's direct access to other layers should one system be compromised.

### VPC and Virtual Network Design

On cloud platforms, virtual network structures form the organization's core cloud architecture.

SecureSys can support the design of the;

- subnet,
- route table,
- internet gateway,
- NAT gateway,
- security group,
- VPN

components.

### Use of Private Subnets

It is recommended that database and critical application servers are not directly reachable over the internet.

SecureSys can place these systems within a private subnet so they are reachable only from the necessary application layers.

### Use of a Bastion Host

A Bastion Host can be used to manage systems within a private subnet.

Example:

**Administrator → VPN/MFA → Bastion Host → Private Cloud Server**

This approach helps prevent the management ports of critical cloud servers being exposed directly to the internet.

### Cloud VPN Integration

VPN connections can be used to provide secure communication between an organization's data center and its cloud environment.

SecureSys can support building;

- Site-to-Site VPN,
- IPsec VPN,
- Client VPN

structures.

### On-Premise and Cloud Integration

In Hybrid Cloud environments, users may need to reach cloud servers securely over the corporate network.

This structure;

**Corporate Network → Firewall → VPN → Cloud Network**

can be built with this architecture.

Routing and security policies are configured by evaluating both environments together.

### Cloud Active Directory Services

Active Directory services can be used in Windows-based cloud infrastructure.

SecureSys can provide support on;

- Domain Controller,
- DNS,
- Group Policy,
- user management,
- hybrid identity

topics.

### Patch Management on Cloud Servers

Applying operating system updates regularly is critically important for cyber security.

In the patch management process, SecureSys can use the;

**Analysis → Backup/Snapshot → Update → Reboot → Verification**

approach.

In production environments, updates can be planned within maintenance windows.

### Cloud Vulnerability Management

Checking vulnerabilities on cloud servers regularly is important.

Depending on the service scope, SecureSys can carry out assessments on;

- operating system vulnerabilities,
- open ports,
- outdated packages,
- security configurations

and similar areas.

### Cloud Server Backup Service

The high availability of cloud environments does not remove the need for backup.

In SecureSys Cloud Backup services, the;

- VM backup,
- disk snapshot,
- application backup,
- database backup,
- offsite backup

structures can be built.

### Snapshot Management

Snapshot technologies on cloud platforms can be used for rapid rollback.

But a snapshot alone should not be treated as a long-term backup strategy.

SecureSys plans snapshot use together with the backup policy.

### Cloud Backup Retention

How long cloud backups are kept should be determined by the organization's business and regulatory requirements.

For example;

- daily,
- weekly,
- monthly,
- yearly

retention policies can be created.

### Offsite Backup

Keeping backups of critical systems only on the same cloud platform can create additional risk.

Where needed, SecureSys can evaluate creating additional copies in a different location or in different backup environments.

### Immutable Backup

The deletion or encryption of backup systems is a significant risk in ransomware attacks.

On supported infrastructure, **Immutable Backup** structures can be used so backups cannot be modified or deleted for a defined period.

### Cold Backup Integration

For highly critical systems, transferring cloud backup data additionally to Cold Backup systems separated from the production environment can be evaluated.

This approach can reduce the risk of security incidents in online systems affecting backups.

### Cloud Disaster Recovery

Cloud environments can offer flexible options for building Disaster Recovery solutions.

Within SecureSys Cloud DR, the;

- secondary region,
- secondary data center,
- replication,
- backup restore,
- failover

scenarios can be evaluated.

### RPO and RTO Management

There are two core targets in cloud backup and DR design.

**RPO – Recovery Point Objective:** The acceptable amount of data loss.

**RTO – Recovery Time Objective:** The target time for the system to become operational again.

SecureSys can plan the backup and DR architecture according to the organization's RPO/RTO expectations.

### Cloud High Availability

Using a single virtual server can create a Single Point of Failure for critical applications.

In its high availability approach, SecureSys can evaluate architectures such as;

- multiple server,
- load balancer,
- cluster,
- multi-zone,
- database replication

and similar designs.

### Load Balancer Integration

A load balancer can be used in structures with more than one application or web server.

A Load Balancer helps provide;

- traffic distribution,
- health check,
- high availability

capabilities.

SecureSys can support the integration of cloud servers with load balancer structures.

### Auto Scaling

For applications with variable traffic, fixed server capacity can be inefficient in terms of cost or performance.

In cloud-native structures, Auto Scaling can bring new resources online as load increases and reduce resources as load falls.

SecureSys can support the design of automatic scaling architectures in suitable projects.

### Cloud Database Management

MSSQL, PostgreSQL, MySQL and other database systems can run on cloud servers.

SecureSys can manage the;

- database deployment,
- backup,
- monitoring,
- performance tuning,
- security,
- replication

processes together with the cloud infrastructure.

### Integration with DBaaS

The application layers of cloud servers can run with managed DBaaS services.

SecureSys can support DBaaS integration by evaluating application connections, network access, security and backup processes together.

### Integration with Container Infrastructure

In modern applications, some services can run on containers rather than virtual servers.

SecureSys can support running traditional cloud VM infrastructure alongside container and CaaS platforms.

### Cloud Log Management

Cloud servers generate many operational and security logs.

These logs can come from;

- operating system,
- authentication,
- application,
- firewall,
- cloud platform

sources.

SecureSys can forward logs to central log management or SIEM systems.

### SIEM Integration

Forwarding the security logs of cloud servers to SIEM increases visibility.

For example;

- failed logins,
- administrator access,
- service changes,
- security events

can be analyzed through SIEM.

### SOC 7x24 Integration

Critical cloud infrastructure must be monitored continuously not only for performance but also for security.

With the SecureSys SOC 7x24 service, events from cloud servers and security services can be analyzed.

In this way;

**Cloud Monitoring + SIEM + SOC**

can be used in an integrated way.

### EDR/XDR Integration

Endpoint-based security visibility can be provided by using EDR/XDR agents on cloud servers.

These systems can help detect attack behavior such as;

- malware,
- ransomware,
- suspicious process,
- credential theft,
- lateral movement

and similar activity.

### Cloud Threat Detection

To detect suspicious activity in cloud environments, the;

- cloud audit logs,
- authentication,
- network logs,
- EDR/XDR,
- SIEM

data can be analyzed together.

SecureSys SOC operations can evaluate this data centrally.

### Cloud Server Security with MFA

Using MFA for administrator and critical user access can reduce the risk of account takeover.

On supported infrastructure, SecureSys supports strengthening cloud management access with MFA.

### Cloud Management with PAM

PAM technologies can be used to control administrator access to cloud servers.

Through PAM, the;

- admin accounts,
- password management,
- access approval,
- session recording,
- time-limited authorization

can be managed centrally.

### Zero Trust Cloud Approach

A system being inside a private network in a cloud environment should not automatically mean it is trusted.

In the Zero Trust approach, access is granted by evaluating the;

- user,
- device,
- source,
- destination,
- time,
- risk

factors together.

SecureSys can strengthen cloud infrastructure with segmentation and access controls in line with Zero Trust principles.

### Cloud Server Security Isolation

Sensitive systems can be placed in network segments separate from standard web and user systems.

For example;

**Public Tier → Application Tier → Restricted Database Tier**

this structure can be used.

In more critical environments, separate security zones and management networks can be created.

### The Red Network and Green Network Approach in the Cloud

Security zones such as Red Network and Green Network do not have to be applied only in physical data centers.

In cloud environments too, different security levels can be created using;

- separate subnet,
- separate virtual network,
- cloud firewall,
- route table,
- bastion host,
- access policies

and similar controls.

For example;

**Green Cloud Network → Cloud Firewall → Red Cloud Network**

this architecture can be designed.

Access to critical systems can be restricted with layers such as Jump Server, MFA and PAM.

### Cloud Cost Management

One of the advantages of cloud infrastructure is the pay-as-you-go model. But when resources are left uncontrolled, cloud costs can rise quickly.

Within SecureSys Cloud Cost Management, cost optimization can be carried out by identifying;

- underused resources,
- unnecessary disks,
- idle VMs,
- old snapshots,
- unnecessary public IPs,
- oversized servers

and similar waste.

### The FinOps Approach

FinOps is the approach that aims for cloud costs to be managed jointly by technology and finance teams.

In cloud operations processes, SecureSys can evaluate the;

- usage,
- capacity,
- cost,
- performance

data together.

The aim is not simply to lower the cloud bill, but to improve the balance between the resources spent and the performance obtained.

### Cleaning Up Unused Cloud Resources

Over time, resources such as;

- unused disks,
- snapshots,
- IPs,
- virtual servers,
- test environments

can accumulate on cloud platforms.

These resources can create unnecessary burden in terms of both cost and security.

SecureSys can carry out periodic resource cleanup and inventory checks.

### Cloud Asset Inventory

Knowing which resources exist in a cloud environment is important for both security and cost management.

In SecureSys Cloud Asset Inventory work, an inventory can be built of resources such as;

- virtual machine,
- disk,
- IP,
- network,
- security group,
- backup,
- database,
- container

and similar assets.

### Cloud Configuration Management

Configuration changes made on cloud infrastructure must be managed in a controlled way.

SecureSys applies the;

**Planning → Change → Test → Verification → Documentation**

approach.

Rollback procedures can be prepared for critical changes.

### Cloud Server Migration

Physical or virtual servers can be moved to a cloud environment.

In Cloud Migration processes, SecureSys can manage the;

- existing system analysis,
- dependency analysis,
- target cloud architecture,
- network,
- security,
- backup,
- test migration,
- production migration

steps.

### Physical to Cloud Migration

In suitable scenarios, physical servers can be moved to a cloud virtual machine environment.

Performance, licensing, network and application compatibility should be evaluated before the transition.

### Virtual to Cloud Migration

VM systems in existing VMware, Hyper-V or other virtualization environments can be moved to cloud platforms.

SecureSys aims to keep downtime to a minimum in the migration plan.

### Cloud to Cloud Migration

Moving from one cloud provider to a different cloud environment is also possible.

In Cloud-to-Cloud migration projects, the;

- data transfer,
- VM conversion,
- network,
- DNS,
- security,
- backup

dependencies are evaluated together.

### Cloud Disaster Recovery Tests

Having built a DR environment is not enough on its own.

In periodic DR tests, SecureSys can verify the;

- backup restore,
- replication,
- failover,
- application access,
- network,
- DNS

scenarios.

### Cloud Backup Restore Tests

Whether the cloud backups taken are genuinely usable must be verified with restore tests.

SecureSys can carry out periodic restore tests to check the effectiveness of the backup policy.

### Cloud Server Documentation

Documenting cloud infrastructure correctly is important for operational sustainability.

Documentation can hold information such as;

- server list,
- IP addresses,
- CPU/RAM,
- disk,
- operating system,
- application role,
- network segment,
- backup policy

and similar records.

### Cloud Network Topology

Documenting the cloud network architecture visually makes operations and security management easier.

The topology can show the;

- virtual network,
- subnet,
- cloud firewall,
- VPN,
- load balancer,
- public/private server,
- database

connections.

### Cloud SLA Management

Different response processes can be defined for critical cloud servers according to incident priority.

Depending on the service model, escalation and response processes can be created at;

- critical,
- high,
- medium,
- low

levels.

### Cloud Incident Management

Service outages occurring in a cloud environment must be managed systematically.

In the Incident Management process, the;

**Detection → Analysis → Escalation → Response → Verification → Closure**

steps can be applied.

### Cloud Problem Management

Resolving recurring server problems only temporarily is not enough.

With a root cause analysis approach, SecureSys aims to investigate the underlying cause of the problem and create lasting improvements.

### Cloud Operations Reporting

Periodic cloud operations reports can present the;

- availability,
- CPU/RAM usage,
- disk capacity,
- critical events,
- backup status,
- patch status,
- cost,
- recommendations

figures.

### Executive Cloud Reporting

Summary reports free of technical detail can be prepared for senior management.

These reports can summarize the;

- service continuity,
- critical risks,
- capacity requirement,
- cloud cost trend,
- security posture

at a high level.

### What Cloud Server Operations Delivers to the Organization

Professional cloud server management contributes to;

- reducing service outages,
- improving performance,
- strengthening security,
- planning capacity correctly,
