Deploying Web Servers in the Cloud: Challenges & Best Practices. A frequent task for developers is to deploy web applications in the cloud. One one hand cloud computing, such as Amazon Web Services, Microsoft Azure or Google Cloud Platform, offers many advantages such as scalability, flexibility and availability. But, deploying applications in the cloud comes with some technical and operational challenges that need to be addressed and resolved.
That is why this article discusses the challenges and best practices of deploying web servers in the cloud. We will look at various aspects such as scaling, security, performance, monitoring and environment configuration. All of these factors are key to maintaining a stable and secure environment running in the cloud. Along with this, best practices for web server and application configuration, such as ensuring security, availability and performance is discussed.
Shall we start with Deploying Web Servers in the Cloud: Challenges and Best Practices.
Introduction of Cloud Computing
What is Cloud computing? It is the sharing of information such as data or storage at your command, in real time. It has caused quite a revolution in the market and especially in the IT industry, it is also known that the valuation of the market is growing at a very fast pace. Progress of the development of the cloud has paid off for everyone small to large companies. It greatly decreases costs.
Challenges of deploying the Web Servers in the Cloud
Multi Cloud environments
The first challenge companies may encounter is the increase in the number of cloud options available to corporations. In the end companies do not rely on using just one cloud. Instead, they subscribe to multiple cloud providers. Quite a common solution is becoming a hybrid cloud. Unfortunately, replying on multi cloud results in infrastructure teams having to manage infrastructure with more difficulty. The processes becomes very varied for IT teams because there are differences between multiple cloud providers.
The second very common challenge is when the vast majority of cloud providers have a so-called ‘Pay as you go’ model. This reduces the cost of the resources used, although there are also situations where a company incurs huge monetary losses when using the cloud. This happens when the servers are not used sufficiently and then additional costs are added. In addition, there is degradation of application performance or definite spikes or overshoots in usage, which also increases costs. Thus, under-utilised resources are the reason that costs go up. In addition, if you enable cloud services and do not switch it off when not in use, this incurs additional costs.
An important factor when considering cloud based solutions is performance. A lack of satisfactory cloud performance results in an exodus of users and a drop in profits. Even a slight delay when loading an application or website causes a huge drop in the percentage of users. Such latency is the result of ineffective load balancing, meaning that the server is unable to efficiently distribute incoming traffic to provide the best user experience. Problems also occur with fault tolerance, meaning that operations continue as required even, if one or more components fail.
Data Security and Privacy
Information security is a major concern when moving to cloud computing. The private information of a user or organisation set aside in such a cloud is basic and private. While the benefit provider guarantees the judgement of the information, it is the responsibility of the client to perform client verification and authorisation, sign management, encryption of information and access control. Security issues in the cloud include personality intrusions, information breaches, malware incidents and more, which ultimately diminish customers’ faith in your applications. This, in turn, leads to a potential loss of revenue near fame and status. In addition, cloud management requires sending and receiving gigantic amounts of information at high speed and is therefore helpless against information leaks.
Lack of Skilled Personnel
Cloud computing requires specialised competencies that many companies may not have in-house, leading to a shortage of qualified personnel who effectively manages and maintains cloud infrastructure.
Best Practices for Top Performance of Web Servers in Cloud
Server performance monitoring enables the proactive identification of potential problems with application servers. What are the main reasons why you should monitor your server and its performance include:
Performance Monitoring and Evaluation
Configure Server Parameters
Configure security on the server in a way that optimises performance. This includes adjusting timeout settings, limiting the number of connections per IP address and configuring server-side compression.
Set up Alerts
Setting alerts helps you to proactively detect any problems with your web servers and applications, such as high CPU usage, low memory or failed requests. This allows you to respond to problems more quickly and prevent downtime.
Monitor for errors
Error monitoring helps to identify problems with your application or web server, such as failed requests or HTTP errors. It also assists in detecting security incidents or attacks.
Control and Monitoring of Network Load
To ensure that the server has sufficient resources to handle incoming requests, it is important to understand the usage patterns and seasonality of the network load. This helps to scale the server where necessary and optimise your application to improve performance.
Perform Server Hardware Optimisation
Check that the server hardware, such as CPU, RAM and disk space, is sufficient to handle website traffic. Upgrading the hardware significantly improves performance.
In addition, let’s look at a few more examples of supporting performance for servers. Below are some additional examples:
- Create meaningful dashboards.
- Align notification channels.
- Configure the right metrics.
Key Practices for Implementing Security and Monitoring Server Activity
What can we change about internet connectivity and user management areas to improve overall system strength? Let us look at below best tips for server security.
- Establish and use a secure connection.
- Secure sockets layer certificates.
- Use private networks and VPNs.
- Monitor login attempts.
- Establish password requirements.
- Use passphrases for server passwords.
- Set password expiration policy.
- Update and upgrade software regularly.
- Remove or Turn Off All Unnecessary Services.
- Set Up and Maintain a Firewall.
- Create Multi-Server Environments.
- Create Virtual Isolated Environments.
The detailed workflow for monitoring your servers will depend on your choice of server monitoring software and the cloud based servers you want to monitor. As your business increases in size and complexity, you need to select and focus a server monitoring system that collects data from each cloud-based system. The general process of server monitoring can be broken down into several examples:
- Identify the most important KPI.
- Set up comprehensive and specific alerts.
- Use log analysis.
- Set baseline KPI values.
- Implement security best practices.
- Choose the right cloud provider.
- Configure server monitoring.
- Use containers.
- Use auto scaling.
Deploying Web Servers in the Cloud: Challenges & Best Practices Conclusion
All in all, many businesses are selecting cloud solutions as a way to increase scalability, flexibility and cost savings. One common application of the cloud is hosting websites and applications. But moving web servers to the cloud comes with some challenges. In this article, we have outlined best practices and ways to deal with these challenges. Some of the key practices are choosing the right cloud provider, using auto-scaling and load balancers, implementing security best practices, setting up server monitoring and log analysis. Also remember to regularly monitor server activity to identify issues and maintain optimal performance.
To conclude, migrating web servers to the cloud is a beneficial solution for many businesses. To achieve the greatest results, however, it is worth following best practice and troubleshooting proactively.
