  • 66% of workers would like to find a flexible job in the coming future.
  • The unalignment of expectations of different parties lead to talent loss.
  • Hybrid working is the best way to resolve the conflict between the younger generation and C-level people.
  • Why does the younger workers’ thinking matter? 

    Because of Covid 19, many companies have adopted work-from-home practices to ensure employee health safety.

    However, when Covid-19 is coming to an end, the mode of working is shifting and it is now deeply dependent on the mindset of the employees. The younger employees are one of the most important stakeholders as they participate in most of the front-end jobs and they will take part in an important role for your company. That is why what they think is an important factor for your office planning strategy.  

    Qatalog and GitLab are the leader in the I.T. industries who recently completed a survey (Killing Time at Work ’22) on research exploring knowledge workers, like I.T. talents whose focus on developing and using knowledge, rather than producing goods or services.

    In this survey, they asked 2,000 knowledge workers – 1,000 in the US and 1,000 in the UK, about the experience of asynchronous work, the barriers to adoption, and its growing importance in the modern workplace. 

    Glossary:  Asynchronous (async) work means that people work in the same team during different times of their own timetable without waiting for a response, it also represents flexible work.

    The expectation of younger generation workers 
     

    Flexibility is critical for retaining talent

    Nowadays, people are seeking to work flexibly as it become a new norm after COVID-19. Based on the survey, we can see there are lots of positive impacts of flexibility on wellbeing. 

    According to research, 79% of the aged 21-34 participants would consider fully remote working because they can have less stress without C-level execs monitoring and be much happier. They also reflected that flexible work can make them work more productively and creates higher quality outcomes.

    Moreover, 43% of people indicated they would consider a lower-paid role if it gave them greater schedule flexibility. The reason is that flexible work gives them more free time to pursue hobbies and other interests outside of work. 

    The conflict between directors and younger workers 

    The expectation of the people, especially the young generation, is to have flexible, asynchronous work. However, some of the administrators still support the traditional working method, such as working at the office and having lots of daily meetings, such as Tesla. The major reason is that C-level people and administrators cannot make sure the workers work in time and keep a high attendance rate.  

    However, flexibility is one of the key factors for companies trying to attract and retain talent. 66% of the young talents would resign from their job if they can’t fight back for the right to work flexibly.  This unalignment of expectations between companies’ directors and younger generation workers would eventually cause talent loss. 

    To reduce talent loss, all you need is to align the expectation between employees and the directors. One of the best solutions is a mixed style of work at the office and from home, i.e., hybrid working

    A perfect system for hybrid working: Bookings ONE 

    Hybrid work means a mixed working style of working at the office and working from home. You can allow your employee to have high flexibility to choose their desirable workspace. Then you can consider how to reduce the operational cost such as reducing the office workspace, and fulfill the expectation of both employees and administrators.

    Bookings ONE, one of the famous management systems, can help you to easily implement hybrid working at ease.  You can easily perform virtual meetings, desk-hoteling and digital office management with our Room Booking, Desk Booking, and Visitor Management features. 

    ONEs Software now has a dedicated page to introduce a series of hybrid working measures to help you solve problems. You may wish to go to https://ones.software/hybrid-workspace/ for further reference.

    軟件可以即要即用?企業級軟件訂閲服務 (SaaS) 的開發 (1) https://ones.software/blog/2019/04/11/saas-001/?utm_source=rss&utm_medium=rss&utm_campaign=saas-001 https://ones.software/blog/2019/04/11/saas-001/#respond Thu, 11 Apr 2019 06:46:42 +0000 http://blog.ones.software/?p=19 軟件訂閲是一個大趨勢,但如何去建立一個成功的系統,就需要相當多軟件工程上的學問。

    自從 2006 年 Amazon 推出自家的雲端運算服務 AWS 開始,雲端運算徹底改變了傳統伺服器架構的使用方法。由每一次都要購買或租借一臺伺服器主機,變成想用多少伺服器資源都可以即時得到,並採納按照實際使用時間來計算收費的資源訂閱 (Subscription) 模式,大大提升架構系統的靈活度和資源分配效率。這種伺服器架構上的革命,造就了 Software as a Service (SaaS) 的興起。

    在這種交付模式(即 SaaS)中雲端集中式代管軟件及其相關的資料,軟件僅需透過網際網路,而不須透過安裝即可使用。用戶通常使用精簡用戶端經由一個網頁瀏覽器來存取軟件即服務。--維基百科

    雲端運算經歷了十餘年的發展,隨著各大科技巨頭如 Microsoft AzureGoogle Cloud 紛紛加入戰團,今時今日雲端運算服務已經發展得非常成熟。雲端運算能提供到一些普通伺服器不容易做到的功能,如專門處理大數據的資料庫 (Big data Database),以及針對地域問題的災難恢復 (Disaster recovery)。這些服務提供極高的彈性,方便了不少軟件開發商去開發新的軟件,而訂閱收費模式亦大大降低了初創企業入場的門檻。

    https://www.cio.com/article/2991767/10-tips-for-running-a-profitable-subscription-based-business.html

    由於雲端運算採取了訂閲收費,軟件的收費模式亦跟隨著由一次性 (one-off) 收費趨向以訂閲收費的形式來供客戶選擇。這個顯然是整個軟件業界的發展方向,例如 Microsoft 和 Adobe, 都將旗下歷史悠久的 Microsoft Office 和 Adobe Photo 分別轉為 Office 365Creative Cloud 這種訂閲式收費軟件。 新的訂閲模式的娛樂服務如 Netflix / Disney+ / Apple TV + 也不斷興起,而Google 最近發佈的 Stadia 更是企圖用訂閲收費的模式,來衝擊整個遊戲業界。

    Every customer interaction is a marketing opportunity. If you go above and beyond on the customer service side, people are much more likely to recommend you. — — Stewart Butterfield, co-founder of Slack


    雖然說軟件訂閲是一個大趨勢,但如何去建立一個成功的系統,就需要相當多軟件工程上的學問。和對普羅大衆的軟件不同,企業對軟件的要求會更加嚴格,因爲整個服務會影響到他們自身的日常商業運作,所以在建立這種系統時,需要注意的項目就比平時更多。今後我會在這裡和大家由以下的方向出發,去探討怎樣去建立一個穩健的軟件訂閲服務。

    1. 系統架構 (System architecture)
    2. 可擴展性 (Scalability)
    3. 高可用性 (High availability)
    4. 安全性 (Security)
    5. 監察與維護 (Monitoring and Maintenance)
    6. 持續發展 (Continuous development)

    那麼,讓我首先講解一下系統架構所需要留意的事項。


    系統架構 (System architecture)

    建立軟件系統的第一步是設計好適合的系統架構,根據不同的商業需求 (Business Requirement) 所設計出的系統架構也會不同。但歸納起來,訂閲服務的系統架構的可以分爲兩大類:單一租戶模式 (Single tenancy) 多租戶模式 (Multi-tenancy)


    單一租戶模式 (Single tenancy)

    單一租戶模式 是為各個客戶設立一套獨立的軟件系統,他們會有獨立的數據庫、服務器、文件存儲空間等等。

    安全且穩定: 絕大部分企業都會重視資料的安全和保密。單一租戶模式的好處在於每個客戶都有完全獨立的系統,不會有用戶之間資料發生衝突的情況發生,也不會因爲其他客戶的使用量增加而影響到自身的系統。單一租戶對於企業來説會是一個極具說服力的方案。

    有彈性及易於管理:所有數據庫備份、系統還原的工作,或者其他的定制服務,單一租戶模式都能夠提供給予客戶。系統也能夠根據客戶的要求更改域名,或者安裝在客戶指定的雲端服務上面。而因為每個服務器都是獨立運作的,用戶可以選擇在不影響業務的時間帶,來進行系統更新。

    單一租戶模式是一個直觀的方案,和傳統的系統分別其實不大,只是將系統由傳統的數據中心轉移到雲端服務之上,而雲端服務的成本也就轉化為系統的訂閲收費。


    租戶模式 (Multi-tenancy)

    和單一租戶模式不同,多租戶模式是以共用系統資源爲主,多個用戶會同時使用同一套系統

    經濟實惠:在商業角度來看,價錢是相當重要的考慮因素,多租戶模式就能通過分享各個用戶的用量,來分攤成本。這就能將現有的資源得到充分利用,以避免服務器資源上的浪費。按照不同服務的性質而有差別,但採取多租戶模式的話,往往就能夠將伺服器的成本降至一成以下

    迅速提供服務:訂閲服務講求的是能否迅速提供服務,使客戶在短時間内就開始使用是重中之重。 單一住戶模式可能需要數天的設立時間,並對系統進行整合測試 (Integration test)、負載測試 (Load test)等等的測試,才能確保實際運行穩定。而多租戶模式則是在已經運行中的系統中,添加新的租戶 (Tenant) 給予客戶。添加用戶往往只要數分鐘便完成,而且系統的穩健程度就得到確保。

    容易監察、維護及更新:完善系統的監察亦是確保服務質素的重要一環。在多租戶模式下,開發者只需要監測一組伺服器的狀態,便可知道所有客戶是否能正常使用系統。而當要修正系統時,只要將修正配置到一組伺服器上就能解決問題,不需要針對個別客戶進行修正。

    用戶回饋和產品發展:多租戶模式往往可以使得產品有更高速的成長速度。每當新功能完成並配置到系統上,所有租戶也能即時受惠。而功能亦能啓發用戶提出新的需求,開發者能根據這衆多的用戶回饋去分析和開發新的功能。

    雖然多租戶模式下的系統是分享了各種資源並降低成本,但要注意的是用戶的資料是必須做好區分。例如可以使用同一個數據庫伺服器,但每個客戶的數據庫必須分開。文件存儲亦是同等狀況,每個客戶儲存文件的文件夾必須分開。即使在資源共享的情況下,數據的安全和保密還是最重要的考慮。


    如何取捨?

    兩種都各有優點,但實際要建立一個系統的時候,到底應該如何取捨呢?恕我直言,我是傾向支持開發多租戶模式,原因是多租戶模式本身是可以作爲單一租戶模式來使用。

    不同的客戶對系統會有不同的要求。如果有客戶提出必須有一個完全獨立的系統時,你可以爲一個客戶另外設立一組伺服器。這組伺服器只是爲了服務這客戶而設,並限制只有該客戶才能使用這個環境,不會添加新的租客。這樣多住戶模式就能簡單地變成單一租戶模式來使用,各取優點。

    總結

    現在多租戶模式的應用是大勢所趨,Slack、Office 365 ,這些軟件都是採用這種系統架構。這樣才可以控制成本,以維持市場上的競爭力。

    多租戶模式似乎有絕對的優勢,但實際上做出一個穩健的多租戶模式系統並不容易,對開發者的系統架構能力也有很高的要求。而系統有任何問題也會影響到全部的客戶。例如系統如不採取一個有效的方法,去將用戶的流量分流到不同的數據庫的話,極有可能會令到系統本身出現混亂,往後亦難以作出維護。

    我們之後會和大家介紹多租戶模式的實踐,由原始碼的層面出發,去看看如何做出一個穩健的多租戶模式架構。更多資訊可以留意 ONES Publication 定期發佈的文章,亦可以聯絡我們,
