[Blog] This is the Challenge of Japan's Web Production Industry! Part 1

The Japanese web production industry should be like this! A perspective from someone who has been involved since the dawn of web business.

In the past, there were many OA companies in Japan that specialized in the proliferation of PCs, handling the purchase, installation, and support (for inquiries about malfunctions or usage) of corporate PCs and software. However, now, companies that outsource such services as standalone entities have almost disappeared. In small and medium-sized enterprises, it is common for knowledgeable employees in the general affairs department to handle these issues, or for system-related employees to manage them as a side task. In Japan, there are still many struggles in providing support, and companies often outsource to specialized firms (including web production companies), general advertising agencies, or internet-focused advertising agencies. Many of these tasks have become less of a trial-and-error process in the United States, allowing companies to focus on tasks that yield better results. [Overview] ■ Perspectives from the dawn of web business ■ The commoditization of the web globally ■ Countries that "create" will gain an advantage ■ Author profile *You can view detailed content of the blog through related links.

[Blog] Introduction to Web Performance: Redirects

Redirect errors lead to performance degradation! Introduction to a blog article.

Websites are no longer just simple HTML pages with static content. They have transformed into dynamic interfaces equipped with various features, and the content is updated at regular intervals. Website administrators use various techniques to allow users to view new versions of pages and content. When new features are added to the site or when web page resources are moved to new locations, users may not want those pages to be accessed. To prevent access, web page redirects are used. This allows the submitted HTTP requests to be redirected to other locations within the site, ensuring a seamless user experience. [Overview] ■ Role of Redirects ■ Types of Redirects ■ Performance Impact of Redirects ■ Common Redirect Errors ■ Proper Implementation of Redirects *For more details about the blog, please refer to the related links.

[Blog] These are the challenges in Japan's web production industry! Part 3

What is the quality of Japanese hospitality? Introduction to an article contributed by veteran web manager Mr. H.

In the previous and the one before that, I expressed my views on the Japanese web industry, but this time I would like to point out the essential concept of "omotenashi," which is crucial for considering the quality of the web, based on my experiences, including its historical transitions. In the service industry, consumer manufacturing, and the web industry, it feels like there is a current trend of actively working on improving customer satisfaction and UX, which I find to be a very positive trend. There is no doubt that improving customer satisfaction and UX contributes to business, and I believe this common understanding has taken root in the web industry. [Overview] ■ What is "Japanese omotenashi" in the first place? ■ Disadvantages of trust-based transactions ■ A failure story from a certain enthusiast ■ Summarizing the changes of the times ■ What Spelldata thinks about customer satisfaction and customer delight ■ Author's profile *You can view the detailed content of the blog through the related links.

The newly updated Google PageSpeed Insights

Analyzing delivery quality with real user data! Introducing two metrics and more on the blog.

On January 9, 2018, Google announced a significant overhaul of PageSpeed Insights on its blog. ("Real-world data in PageSpeed Insights") Previously, Google PageSpeed Insights was a scoring tool that assessed compliance with best practices but did not evaluate actual display speed. With the changes in January, Google PageSpeed Insights began utilizing data from users browsing with Chrome to present statistical analyses of display speed. However, there are sites that receive assessments and those that do not. Why is that? Understanding the background of this new system will clarify the reason. [Overview] ■ A major transformation of Google PageSpeed Insights ■ Quality of delivery displayed by percentile values ■ Two metric values ■ Sample acquisition ■ Speed assessment ■ Important points to note *For detailed content of the blog, you can view it through the related link.

What can we learn from AWS's "December Outage Festival"?

Four Points for Companies to Prepare for Internet Disruptions! Introduction to a Blog Article

The series of internet outages and disruptions that occurred in 2021 demonstrate how interconnected and relatively fragile the internet ecosystems are. For example, there were three consecutive outages of Amazon Web Services (AWS) in December. These outages vividly illustrate the fact that "there is no distinction between large and small when it comes to service failures." 【Overview】 ■1. Early detection is crucial for responding to incidents like the AWS situation. ■2. Comprehensive observability enables rapid response during incidents. ■3. Ensuring corporate availability and business continuity cannot be achieved through individual efforts alone. ■4. Monitoring solutions installed in the environment being monitored are insufficient. *You can view the detailed content of the blog through the related links.

Are you losing valuable productive time of your employees simply because you lack observability?

The importance of early warning systems for detecting earthquakes and tsunamis, military defense, and crises in business and finance has long been understood. So why are service providers, especially those offering SaaS (Software as a Service), not doing the same? In a world where a minute can even translate to millions of dollars, it is crucial to carefully monitor the supply chain and delivery chain of services to corporate and consumer end users. *For more details, please refer to the related link.
