What is a Web Server and an Application Server? 7 Main Benefits of an App Server

Fast data retrieval is a need for the 21st century. The data transmission rate can greatly impact application response time, especially when it involves gaming, video editing, website hosting, AI, and machine learning.  SDDs evolved to overcome the shortcomings of hard drives. SSDs, in contrast to HDDs, utilize flash memory, which translates to performance. However, because of the SATA connection, standard SDDs failed to deliver high-performance storage solutions. That’s where PCIe and NVMe came in. This guide provides insights on NVMe vs SSDs. Is SATA a suitable option? Is NVMe good for server and hosting needs? What are the different variants?  SSD Variants There are several variants of solid-state storage, each with its unique characteristics and use cases. Solid-state drives come in different forms utilizing different hardware interfaces ie. IDE/PATA, SATA, and PCIe.  Here are all the different variants of SSD available in the market: IDE (Integrated Drive Electronics) / PATA (Parallel ATA): These SSDs are found in legacy systems. They use 40- or 80-pin connectors and are relatively slow because they are based on older technology. SATA(Serial ATA): In early 2000, the SATA became the industry standard. It uses 7-pin data and a 15-pin power connector. The generation of SATA interfaces matters. SATA I can offer 150 MB/s or 1.5 Gbit/s. SATA II and SATA III can offer 300 MB/s (~3 Gbit/s) and 600 MB/s (~6 Gbit/s) respectively. SATA SSDs are available in three distinct form factors: 2.5-inch, 3.5-inch, and mSATA. mSATA: The compact size of mSATA makes it a perfect fit for notebooks, laptops, and tablets. SCSI/SAS: SCSI can connect multiple devices to a single host adapter. It finds its application in legacy server racks. SAS is the recent version of SCSI. SAS can offer transmission rates up to 12 Gbps or 24 Gbps. Such speed enhancements make it suitable for data centers and enterprise storage. PCIe: PCIe establishes a fast connection directly to the CPU and underlying storage device, bypassing traditional interfaces. This direct connection makes high throughput possible. NVMe, utilizing PCIe, delivers ultrafast data transfer and improves application response time. NVMe can offer up to 2 GB/s or 4GB/s per lane. For instance, a 4-lane interface can reduce the transfer time almost by 4 times.  NVMe vs SSD Standard SSDs are designed to interface through SATA, whereas NVMe SSDs leverage PCIe ports for enhanced performance. PCIe transmits data through lanes, with each lane capable of transmitting data in both directions simultaneously (full-duplex).  Performance An NVMe SSD can be 20 times faster than a normal SSD. The ‘e’ in Non-Volatile Memory Express refers to a PCIe bus.  Gen 4.0 NVMe SSD can deliver up to 7500 MB/s while Gen 5.0 NVMe SSD can double that speed reaching 14500 MB/s. Contrary to this, a SATA SSD can deliver up to 500 MB/s. Despite the significant data transmission rate gap, it barely affects personal computing. However, in cloud and hosting solutions, it matters. When a server handles 1k simultaneous requests, high-speed SSDs shine with their I/O efficiency, boosting performance and ensuring smooth service even during peak demand. Power NVMe SSDs can consume more power than SATA SSDs, typically around 4-8 watts under load and 1-3 watts under idle conditions, due to the power-intensive PCIe interface.  Cost Despite the slightly higher price of NVMe-enabled SSDs, this reflects their superior performance capabilities compared to SATA III SSDs. NVME Advantages over a Normal SSD Parallel Data Transfer: NVMe leverages multiple lanes to transfer the data, unlike serial communication protocol, where only one bit of data can be transferred at a time. This in turn, improves data bandwidth and throughput. Occupies Less Space: NVMe comes in M.2 and U.2 form factor.  M.2 drives are 22mm wide x 80mm long while the majority of standard SSD comes in a 2.5-inch form factor and has dimensions 69.85mm wide x 100mm long x 7mm (or 9.5mm) thick. With modern laptops and motherboards, you can connect two M.2 drives at the same time. Faster Speed: In the previous section, we already made a comparison of speeds offered by NVMe in contrast to normal SSD. What to Look for in an NVMe Storage It's important to note that NVMe SSDs can vary in performance, endurance, and functionalities, which can have a substantial impact based on the specific use case. PCIe Gen 3 vs Gen 4 vs Gen 5 PCIe has evolved, with newer generations offering faster data transfer speeds and improved performance.  PCIe Gen 3 provides a maximum data transfer rate of 8 Giga transfers per second (GT/s) per lane, while PCIe Gen 4 doubles this to 16 GT/s per lane. PCIe Gen 5, the latest generation, further increases this to 32 GT/s per lane. Gen 4 doubles the bandwidth offered by Gen 3. PCIe Gen 4 still holds the bet for consumer markets. Form Factor These drives come in different physical sizes. M.2: M.2 are small-size drives that fit directly into the motherboard, ideal for laptops and desktops. SATA SSD also comes with M.2 form factor. U.2: Used in server and enterprise environments, connects via PCIe slots and typically offers higher endurance. U.2 comes with a 2.5-inch form factor PCIe Add-in Cards (AIC): Larger and used primarily for server or high-performance applications, requiring a dedicated PCIe slot. Heat Sink Many high-performance drives come with built-in heatsinks to help dissipate heat. Some Gen 4 drives, like the Samsung 980 Pro or Western Digital Black SN850 come with a heatsink for improved performance. Endurance (TBW or DWPD) TBW (TerraByte Written) shows the total data that can be written to the drive over its lifespan, while DWPD (Drive Writes Per Day) indicates how often the entire drive can be written per day, typically over 5 years. Hosting Aspect Opting for NVMe-based SSDs instead of SATA SSDs in hosting and SEO can have a substantial effect on performance and user experience. A bad user experience can hurt SEO rankings and visitor engagement At Hostman, you can grab NVMe-enabled cloud servers for $2 per month. Latency In a hosting environment, low latency is critical for ensuring fast and efficient data access and transfer. NVMe SSDs offer lower latency than SATA SSDs. This means faster response times for your website, especially in situations with high traffic or complex database queries. Uptime A high-performance drive is designed to provide reliable and continuous access to data over an extended period. It is built with enterprise-grade components and features that enable it to withstand heavy workloads and maintain its performance levels even under high-stress conditions. The drive may include features such as power loss protection, which helps ensure that data is not lost or corrupted in the event of a sudden power outage. Here, at Hostman, we provide 99.98% uptime. User Experience SEO involves not only rankings but also user experience. Hosting on NVMe-enabled servers can speed up website load times, keeping visitors engaged and potentially reducing bounce rates. For e-commerce stores, this could lead to improved conversion rates. Conclusion If you're running a smaller website with minimal traffic or non-resource-heavy content, you might not need to migrate just yet.  For SEO, speed is a critical factor. Google considers page load time and Core Web Vitals as ranking factors, meaning faster websites are more likely to rank higher.  If you're seeing slow page loads, frequent throttling, or lag during peak traffic times with traditional SSD hosting, NVMe hosting might be just the upgrade you need to avoid losing users and boost your rankings. Similarly, if you run a high-traffic website, such as an e-commerce store, media platform, or blog with rich multimedia content, the performance boost from NVMe storage can be a game-changer.  Upgrading to NVMe web hosting can improve the website’s performance. With Non-Volatile Memory Express hosting, you get top-tier speed, reliability, and efficiency, far exceeding traditional SSD hosting. However, NVMe's power isn’t always necessary for every type of website.

Creating a website for a business or organization can present many challenges. What sort of content should be included? While browsing, how will mobile apps affect functionality? And crucially, you need to decide whether your business’ needs are best suited by a static or dynamic website. This article will help you decide which type of website is best for your purposes. We will lay out the advantages and disadvantages of each kind of website to help you differentiate and decide between the two. What’s the difference? When the internet was still in its infancy, the only type of website you’d be able to find were static websites. If you wanted to change or update something on your site, a human web developer would need to change the code directly. But as technology progressed, web developers began to create dynamic websites. These are websites that can dynamically access and display content when requested. Not every website needs to be dynamic, but some static websites can use dynamic functions to create a kind of hybrid of the two. An example of this kind of hybrid site would be a website for a vacation resort that integrates local weather forecasts into its homepage. For some, a well laid-out static website is sufficient for their business’ needs. It really depends on the purpose of your website and how much flexibility you need to provide the user. Code and delivery A website with static code will not change unless a web developer edits it. On the other hand, a dynamic website is built by accessing a database to deliver content in real-time. Static web pages are pre-rendered for the user and look the same no matter from where or how they accessed. The web developer can know exactly what the user will see when they arrive at the website. Meanwhile, a dynamic page is generated by a server. It can also look different depending on the location from where it would be accessed to which browser is being used. Static Websites A static web page, also known as a flat page or stationary page, is usually coded in HTML, CSS, and Javascript. Static web pages, also known as flat or stationary web pages, are essentially a viewable document only editable with the right coding skills. Regardless of where the page is accessed from, or who is accessing it from the host server, the page appears the same as when it was originally created. In order to make your static website go live easily, you can deploy it with tools such as Hostman. Let’s take a look at some pros and cons of static websites. Pros Simple to set up: Static websites present far less complexity than their dynamic counterparts and so are easier to set up. There is a wide range of website builders that can help you do this. Speedy process: The ease of setting up static web pages means that it’s a speedy process. If you need to get something up in a hurry, static websites might be the best choice for you. Lower Costs: The simplicity of static websites means they tend not to take up a lot of space. The result is that they are cheaper to host. Stability: As the content on a static website is unchanging, it’s far less likely to malfunction. This makes usability testing a breeze. Performance: The simplicity and stability of static web pages allow them to load quickly for the user. This quick performance is a result of the efficient coding languages used to create them. More Secure: Without the need to utilize third-party software, databases, or a CMS (Content Management System, more on that later), static websites allow for fewer potential vulnerabilities than a dynamic website. Cons Updates: Without the prerequisite coding skills, updating a static website is difficult. A web developer would likely be required, eating into your initial setup savings. Limited: It’s entirely possible to build a larger static website, but that would be a long and labor-intensive process. This is because each time a new page is required, it needs to be built from scratch. A template can help, but that will only get you so far. Tired content: Without giving visitors to your website a reason to return, you may find traffic numbers stagnate. Static websites are less well suited to the adding of lots of fresh content to keep users coming back for more. User Interaction: Static websites don’t provide opportunities to engage with active, up-to-the-minute content. Ongoing costs: As your website grows, if the static model is what you’re sticking with, you’ll require a larger team to manage it, therefore increasing costs. On mobile: A static website that looks fantastic on a laptop may not appear so well on a mobile device. According to Statista, 56.89% of global internet traffic was through mobile devices as of February 2022. Dynamic Websites Written in more complex programming languages such as CGI, Ajax, or ASP, dynamic websites are presented to users with the help of databases. Users can experience a dynamic website differently depending on a number of factors. A user looking at a website through Safari on an iPhone versus one viewing through Chrome on a laptop may see different content, better tailored to them individually. What is a CMS? Content Management Systems are vital software for the functioning of dynamic websites. They allow multiple users to publish or edit content on the site. A CMS is often essential to ensuring quality user experience on a dynamic website, and can be used to schedule content posts for a later date and edit old content. It’s well worth considering if a CMS might be useful for your business’ website. If you do, ensure whichever one you choose has undergone rigorous software application testing. Let’s now take a look at some of the pros and cons of dynamic websites. Pros Easy updates: It is much easier to update dynamic websites, which is a significant advantage. With the help of a CMS, multiple people within an organization can contribute without any specialist coding experience. More volume: Thanks to the way dynamic websites are structured, it is much easier to provide much more content than possible with a static website. You can offer hundreds of searchable pages and drive more traffic to your website. Just make sure you have the best database management tools to help you. Sleek design: Dynamic websites allow an organization to put on a more professional face when compared to static websites. This type of website also provides increased flexibility for design choices. Tailored Content: By taking advantage of cookies, demographics, and keyword research, a dynamic website enables you to present content that will most appeal to different groups of users. The website is able to recognize if you’ve got a new visitor and even present special offers for new potential customers. Mobile device optimization: As a dynamic website can recognize the type of device being used to access it. It can also adapt to present itself just as well on a mobile device as on a laptop or tablet. Discoverability: More content and a great design makes your website easier to find. A dynamic website, in tandem with good keyword research, brings higher traffic volumes. If discoverability is a priority for your organization’s website, it’s well worth taking the time to learn what is keyword research? Cons Start up cost: You will have to outlay more in the early stages. Even so, ongoing maintenance and updates are fortunately easier and cheaper than static websites. 404: Errors are more likely with a dynamic website. This is a result of the way it needs to access outside databases and shows why testing is vital. For advice on how to mitigate this, head on over to Global App Testing. Security Concerns: By using outside applications and databases, your site is exposed to a greater risk to security. Load times: Due to increased complexity and more content, it’s likely that a dynamic website will be slower to load. Be wary that this can cause visitors to leave. Choices Now that you’ve seen the differences between static and dynamic websites, you need to decide which is best for you. For a small organization whose requirements amount to an online brochure, a static website might make the most sense. These days, having a website is essential for a small business. As long as you don’t need to constantly update content, a static website might be the way to go. For a larger organization, especially one that operates mostly online, a dynamic website can offer the flexibility and room for growth that you will require. For example, a business offering a commercial phone system would want to reach a variety of customers with tailored content presented in a sleek, professional way. A hybrid approach may be best suited for some organizations. A website for a tour operator, for example, may have a lot of content that doesn’t change very often, and use static web pages to feature this content. They would be well served to also set up dynamic elements to the website to reflect changing accommodation and transport costs. Expertise Whichever approach suits your purposes best, ensure you have the right people to help. There are many services and web developers available to help you deliver a quality experience for your website visitors. Choosing the right approach, and executing it well, will give you an edge in attaining online success.
